0:00:02 > 0:00:03My name's Steve Backshall.
0:00:04 > 0:00:06You can call me Steve.
0:00:09 > 0:00:11I'm on a mission to find the Deadly 60.
0:00:11 > 0:00:12Ow!
0:00:12 > 0:00:15That's 60 deadly creatures from around the world
0:00:17 > 0:00:19And you're coming with me every step of the way.
0:00:19 > 0:00:21Ow!
0:00:30 > 0:00:33During the making of Deadly 60,
0:00:33 > 0:00:38we travelled 6 continents, looking for 60 deadly animals.
0:00:38 > 0:00:41Ow!
0:00:41 > 0:00:43Quicker, faster, faster, whoa!
0:00:43 > 0:00:46It wasn't just the creatures we were seeking that were lethal.
0:00:46 > 0:00:52Sometimes, the locations themselves were the biggest challenge.
0:00:52 > 0:00:55And that's what this programme is all about.
0:00:55 > 0:01:01How do we make wildlife films in the most extreme places on the planet?
0:01:05 > 0:01:08Two of the most challenging places we filmed Deadly 60,
0:01:08 > 0:01:12were way up in the Arctic circle, in Alaska.
0:01:12 > 0:01:16And in the humid rainforests of the Amazon.
0:01:16 > 0:01:20And that's where this "Making Of" programme begins.
0:01:22 > 0:01:25When you're filming, it's kind of hard to travel light.
0:01:26 > 0:01:31All these bags and boxes are filled with camera and sound kit,
0:01:31 > 0:01:34filming lights, hi-tech communications equipment,
0:01:34 > 0:01:36and all the other kit you need to launch an expedition
0:01:36 > 0:01:38into total wilderness.
0:01:38 > 0:01:42And, of course, an extra big bag for all my shoes and make-up.
0:01:50 > 0:01:54Two days, three planes, two trucks,
0:01:54 > 0:01:59and one very dodgy looking ferry ride later,
0:01:59 > 0:02:02and we were deep in the Amazon rainforest.
0:02:04 > 0:02:08While we unpack the kit, let me introduce you to my team.
0:02:10 > 0:02:15Deadly 60, I think, more than any other series I've ever worked on,
0:02:15 > 0:02:16is all about crew.
0:02:16 > 0:02:19We've really become like a tightknit family,
0:02:19 > 0:02:20which is really good because,
0:02:20 > 0:02:23I think, when you're climbing cliffs and handling venomous snakes,
0:02:23 > 0:02:26you want to think you can rely on everyone else.
0:02:26 > 0:02:29- This is Charlie, our researcher. Say hello.- Hello.
0:02:29 > 0:02:33Mark, who's behind the camera at the moment.
0:02:33 > 0:02:35- That's Mark.- That'll be me!
0:02:35 > 0:02:37This is Rich, our sound recordist.
0:02:40 > 0:02:44This is Dudu. Dudu is our fixer here in Brazil, and also knows
0:02:44 > 0:02:46a lot about the animals.
0:02:46 > 0:02:49Just there, at the back of the jeep, is James,
0:02:49 > 0:02:52the guy who looks a bit like a rugby player,
0:02:52 > 0:02:54funnily enough, cos he is one!
0:02:54 > 0:02:57James is the director, so his job is...
0:02:57 > 0:03:00to write all the scripts, which I promptly then ignore
0:03:00 > 0:03:02and say exactly what I want to say!
0:03:02 > 0:03:06- That would be funny if it wasn't true!- Yes!
0:03:06 > 0:03:07THEY LAUGH
0:03:07 > 0:03:10There are more species of animals in the Amazon
0:03:10 > 0:03:12than anywhere else on earth.
0:03:12 > 0:03:14Magnificent.
0:03:23 > 0:03:28But catching them on camera isn't as easy as it may seem.
0:03:28 > 0:03:32At the beginning of every shoot, we have to sort out all the equipment.
0:03:32 > 0:03:36That can take half a day just to get all the equipment up and running.
0:03:36 > 0:03:39So there's an awful lot to do before we actually go out in the field.
0:03:41 > 0:03:43Was that OK?
0:03:45 > 0:03:48The cameraman's the guy who films the programme.
0:03:48 > 0:03:51But pictures are only half the story.
0:03:51 > 0:03:53The rest is down to soundman Rich.
0:03:55 > 0:03:56During the programme,
0:03:56 > 0:04:00you've probably seen me running round with my big, heavy kit on me,
0:04:00 > 0:04:02like that. I'll just quickly show you how it all works.
0:04:02 > 0:04:04I'm a bit like the DJ, this is a mixer.
0:04:04 > 0:04:07So all the sound comes in from Steve, from the animals,
0:04:07 > 0:04:09from the experts, it all comes to me.
0:04:09 > 0:04:13And I send it up to the camera on the back of Mark,
0:04:13 > 0:04:16using this radio link. All very clever. Happy days.
0:04:18 > 0:04:23From here on in, it's just your average walk in the woods.
0:04:27 > 0:04:31Well, if your local woods are alive with snakes
0:04:31 > 0:04:33and the world's biggest spider.
0:04:35 > 0:04:39And to get up close to them, and so you feel part of the team,
0:04:39 > 0:04:42we tend to film things slightly differently on Deadly 60.
0:04:45 > 0:04:48This series is a little bit unusual
0:04:48 > 0:04:53in that we don't always just have the one main camera, this one here,
0:04:53 > 0:04:55filming me wherever I'm going.
0:04:55 > 0:04:58We also have...a second camera.
0:05:00 > 0:05:03This guy here can always film what's going on, not just with me,
0:05:03 > 0:05:05but with the main camera.
0:05:05 > 0:05:09And then, especially if we're going somewhere a little bit different,
0:05:09 > 0:05:14like this cave behind me, we can also use a camera like this one,
0:05:14 > 0:05:17which shows you exactly...
0:05:17 > 0:05:18what I'm seeing.
0:05:23 > 0:05:25Perfect.
0:05:26 > 0:05:29These tiny cameras are vital when I'm cramming myself
0:05:29 > 0:05:32into dark and dingy places,
0:05:32 > 0:05:37like this cave, where we were hoping to find vampire bats.
0:05:39 > 0:05:42The sweltering inside of the cave offered no relief
0:05:42 > 0:05:44from the jungle heat.
0:05:44 > 0:05:48Being in this jungle is like being in a steam room.
0:05:52 > 0:05:56Even when it's dark, it's still sticky, hot and wet.
0:05:58 > 0:06:02Filming for the Deadly 60 has taken us to lots of extreme environments
0:06:02 > 0:06:05around the world, like the rainforests here in Brazil.
0:06:05 > 0:06:09The heat and humidity can make it an absolute nightmare for filming.
0:06:09 > 0:06:14And this place is called a rainforest for a reason.
0:06:14 > 0:06:19Sometimes, it seems the rains here will never, ever stop.
0:06:19 > 0:06:23Look at that, like a little glow-in-the-dark brooch.
0:06:24 > 0:06:28Tropical rainforest. No, tropical storm!
0:06:28 > 0:06:30Ha-ha!
0:06:33 > 0:06:36It may look like a kind of hell,
0:06:36 > 0:06:41but, for a wildlife enthusiast like me, it's actually heaven.
0:06:41 > 0:06:45There are wild surprises lurking everywhere.
0:06:47 > 0:06:5124 hours in this place can reveal 100 living treasures.
0:06:51 > 0:06:54Well worth putting up with a little discomfort.
0:07:03 > 0:07:04Whoa, no!
0:07:07 > 0:07:10That's a proper tarantula!
0:07:16 > 0:07:19- Right there.- Wow. Oh, my goodness!
0:07:23 > 0:07:25How did I not get bitten there?!
0:07:29 > 0:07:32Lovely colours.
0:07:33 > 0:07:35Look at that!
0:07:40 > 0:07:43However well prepared our team may be,
0:07:43 > 0:07:47the jungle must never be taken lightly.
0:07:47 > 0:07:49Close calls are all too frequent.
0:07:52 > 0:07:55On a snake search in this flooded forest,
0:07:55 > 0:07:58the animals were the least of our worries.
0:08:01 > 0:08:03THUMP
0:08:03 > 0:08:05You OK?
0:08:05 > 0:08:07You all right?
0:08:12 > 0:08:15Huge branches in the canopy above die and rot,
0:08:15 > 0:08:17or are eaten through by termites.
0:08:17 > 0:08:19They can weigh as much as a car.
0:08:19 > 0:08:22When they fall, it's one of the most deadly things in the jungle.
0:08:22 > 0:08:26Fortunately, no-one was hurt... Just a little bit shocked.
0:08:34 > 0:08:37Sailing down the mighty Amazon, we came upon a floating village,
0:08:37 > 0:08:40where they were breeding a certain Amazonian river fish.
0:08:44 > 0:08:48I hopped into a pool to try and get a closer look.
0:08:56 > 0:08:58And nearly got my head taken off!
0:08:58 > 0:09:01I just got belted in the head by an arapaima!
0:09:07 > 0:09:10Believe it or not, these are small for an arapaima.
0:09:10 > 0:09:15They could easily weigh five times as much as any one of these.
0:09:15 > 0:09:18I'm very glad I didn't get head-butted
0:09:18 > 0:09:20by one of those monsters.
0:09:22 > 0:09:24Obrigado, obrigado!
0:09:34 > 0:09:35Just after dawn,
0:09:35 > 0:09:38and the crew are preparing for a flight in a flying boat.
0:09:40 > 0:09:44We're in search of one of the most remarkable beasts on the series.
0:09:49 > 0:09:52What about actually mentioning the animal... Not naming it,
0:09:52 > 0:09:54but saying there's one animal I want to find,
0:09:54 > 0:09:57- and it's in a really remote location. - Yeah, that's a great idea.
0:09:57 > 0:09:59- That's more of a tease.- OK.
0:09:59 > 0:10:00That's what you're doing.
0:10:00 > 0:10:03They've got big brains, they hunt in packs,
0:10:03 > 0:10:09they're turbo-charged and they're...pink.
0:10:09 > 0:10:12Pink river dolphins. Bizarre is not the word.
0:10:13 > 0:10:16We're going off today to try and film pink river dolphin.
0:10:16 > 0:10:20And I think it's probably about 200 miles in that direction.
0:10:22 > 0:10:24I love my plane, I want one!
0:10:24 > 0:10:28It's just the most wonderful toy, isn't it? It's beautiful.
0:10:28 > 0:10:33And, in order to be able to film the dolphin,
0:10:33 > 0:10:38we're taking with us an underwater camera. Steve's going to have that.
0:10:38 > 0:10:41The big main camera, which I'll be using.
0:10:41 > 0:10:43Unfortunately, it's not very big,
0:10:43 > 0:10:46so it can't more than myself, Mark and Dudu.
0:10:46 > 0:10:48The rest of the crew are a bit miserable,
0:10:48 > 0:10:50cos they've got to sit here.
0:10:50 > 0:10:54Because we don't have enough space on the plane to take a sound man,
0:10:54 > 0:10:57the translator is going to become Rich, the sound man.
0:10:57 > 0:11:00And he'll be doing the sound for me.
0:11:00 > 0:11:03Cos it's myself and Steve, effectively, going off
0:11:03 > 0:11:07and trying to achieve what a group of five or six of us would normally do.
0:11:10 > 0:11:13This radio mic will pick up everything I say.
0:11:13 > 0:11:15Let's load up.
0:11:15 > 0:11:18Including Dudu, our temporary sound man.
0:11:18 > 0:11:20Where's the brake?
0:11:20 > 0:11:23Unfortunately, though, the pilot wouldn't let me drive!
0:11:23 > 0:11:28With no solid land to make a runway, in the Amazon, it's either a boat,
0:11:28 > 0:11:31or a plane that can take off and land on water.
0:11:32 > 0:11:34Or I guess you could swim!
0:11:42 > 0:11:46Seemingly endless forests stretch to the horizon.
0:11:46 > 0:11:50There's a lifetime of exploring and undiscovered animals hidden below,
0:11:50 > 0:11:54but, yet again, the weather is king.
0:11:55 > 0:11:58We've just been hit with the curse of the Amazon,
0:11:58 > 0:11:59well, of all rainforests.
0:11:59 > 0:12:04We've just flown into a bank of solid cloud and rain.
0:12:04 > 0:12:09And, unfortunately, the hydro plane can't get above or below it.
0:12:09 > 0:12:13So we're going to have to turn around and head back to the boat.
0:12:13 > 0:12:17It's bad news for now, but hopefully we'll get another crack at it.
0:12:21 > 0:12:23We're going to have to come up with a Plan B.
0:12:23 > 0:12:27I, for one, am not leaving without seeing our dolphins.
0:12:29 > 0:12:32We sail our giant river boat right through the night,
0:12:32 > 0:12:35and the next day, get a second chance.
0:12:35 > 0:12:38OK, so we may not have succeeded with our seaplane,
0:12:38 > 0:12:41but we don't give up easy on the Deadly 60.
0:12:41 > 0:12:46So this strange-looking, green floating thing is, I think,
0:12:46 > 0:12:49our best opportunity of getting close to pink river dolphins.
0:12:52 > 0:12:53And can we see any?
0:12:58 > 0:13:00Oh, look at that, look!
0:13:00 > 0:13:03I don't believe it, look, look, look, look.
0:13:03 > 0:13:09They're so close. This is going to be very, very special indeed.
0:13:09 > 0:13:12I think it's probably worth just slipping straight in.
0:13:18 > 0:13:19Hello!
0:13:19 > 0:13:26I should say straight off that these are totally wild dolphins.
0:13:26 > 0:13:27Wow!
0:13:30 > 0:13:32Totally wild!
0:13:32 > 0:13:35But the reason they're here is actually...
0:13:37 > 0:13:39..exactly the same reason why they're deadly.
0:13:39 > 0:13:44These animals have huge brains, they're really intelligent.
0:13:44 > 0:13:47Oh, crikey!
0:13:47 > 0:13:49In the finished programme,
0:13:49 > 0:13:53the sequence with these magical river beasts lasts for just a matter of minutes.
0:13:53 > 0:13:57In reality, it took two full days to film.
0:13:59 > 0:14:02Swimming in water the colour of warm cola,
0:14:02 > 0:14:06these pink dolphins use sophisticated sonar and teamwork
0:14:06 > 0:14:08to hunt fish as fierce as piranha.
0:14:08 > 0:14:13They're perfect for the Deadly 60 and well worth the effort.
0:14:15 > 0:14:20River dolphins are on the Deadly 60.
0:14:20 > 0:14:25Even seemingly simple sequences can take an eternity to get right
0:14:25 > 0:14:27if luck isn't on your side.
0:14:27 > 0:14:31Filming the opening to the Amazon programme should have been easy.
0:14:31 > 0:14:33One o'clock in the morning,
0:14:33 > 0:14:36we're doing the opening sequence to the programme,
0:14:36 > 0:14:38which is Steve jumping off the front of the boat.
0:14:38 > 0:14:40Unfortunately...
0:14:40 > 0:14:45the water is only about two metres deep where we were originally moored.
0:14:45 > 0:14:48So we're having to move the boat a little bit further upriver,
0:14:48 > 0:14:51so that Steve's not going to bang his head off the bottom, really.
0:14:51 > 0:14:54Yeah, we're going to use the boat to full effect,
0:14:54 > 0:14:58so Mark the cameraman is going to be in one of the little boats,
0:14:58 > 0:15:02touring around our big mother ship.
0:15:02 > 0:15:05And then, I think I'm going to dive overboard...
0:15:05 > 0:15:06in spectacular fashion.
0:15:11 > 0:15:14We're here...in Brazil.
0:15:14 > 0:15:18And this is the Amazon rainforest, the largest jungle in the world.
0:15:20 > 0:15:24When you see the programme in its final cut version,
0:15:24 > 0:15:27this sequence will take about ten seconds on screen,
0:15:27 > 0:15:30but it's actually... We've been going for about half an hour
0:15:30 > 0:15:34just to make the sequence and we're still nowhere near halfway through.
0:15:34 > 0:15:38So what are we doing on a boat? Well, right here...
0:15:38 > 0:15:42The boat's drifting, the water's not the right depth...
0:15:42 > 0:15:46we can't get the camera shot, the sound's all over the place.
0:15:46 > 0:15:50So, yeah, it's taking a little bit longer than we thought initially,
0:15:50 > 0:15:52but that's TV.
0:15:52 > 0:15:55- Stand by, then.- Camera's at Steve.
0:15:55 > 0:15:56And action.
0:15:56 > 0:15:59We're here, in Brazil in South America.
0:15:59 > 0:16:02And this is the Amazon rainforest, the largest jungle in the world.
0:16:02 > 0:16:05So what are we doing on a boat? Well, round here, this time of year,
0:16:05 > 0:16:09an awful lot of that forest is underwater.
0:16:15 > 0:16:18A whole morning later, finally we're happy.
0:16:22 > 0:16:26All that work for just 15 seconds of telly.
0:16:35 > 0:16:37But finished just in the nick of time,
0:16:37 > 0:16:41cos here comes the rain again.
0:16:44 > 0:16:47So that's how we deal with the rain, the heat and the humidity.
0:16:47 > 0:16:50Now for something completely different.
0:16:53 > 0:16:56We're on another Deadly 60 mission.
0:16:56 > 0:17:01And a good portion of all this kit is woolly gloves and down jackets.
0:17:01 > 0:17:03We're heading to the frozen north.
0:17:10 > 0:17:15This is Alaska, and there's a new team on board.
0:17:15 > 0:17:17Johnny on camera, Nick running sound.
0:17:17 > 0:17:20And taking charge of the directing is Rosie.
0:17:25 > 0:17:26Whoo!
0:17:26 > 0:17:31That is like stepping into a deepfreeze.
0:17:31 > 0:17:35Off there in the distance are the mountains of northern Alaska.
0:17:35 > 0:17:39That way are frozen seas that head all the way to the North Pole.
0:17:43 > 0:17:46Temperatures here can be the same as inside your freezer box at home.
0:17:46 > 0:17:50But there are animals that thrive in these extreme conditions.
0:17:50 > 0:17:53Wow, he's huge!
0:17:53 > 0:17:58But we're here to find the world's largest land predator.
0:18:00 > 0:18:05This flat, snowy expanse is known as the Arctic tundra.
0:18:05 > 0:18:08It's one of the bleakest habitats on the planet.
0:18:08 > 0:18:11Right now, we've got a beautiful blue sky, sunshiny day,
0:18:11 > 0:18:14but even so, it's probably minus 15 degrees centigrade.
0:18:14 > 0:18:19Even in the middle of summer, it rarely gets above freezing here.
0:18:19 > 0:18:22And, in the middle of winter, minus 40 isn't unusual.
0:18:22 > 0:18:26Any animal that can make it here has to be as tough as nails.
0:18:26 > 0:18:30And the animal we're here looking for is probably the hardest.
0:18:30 > 0:18:32It's the largest carnivore that lives on land,
0:18:32 > 0:18:36and probably the most iconic animal of the whole of the frozen north -
0:18:36 > 0:18:38the polar bear.
0:18:41 > 0:18:44With a fully-grown male weighing over half a tonne,
0:18:44 > 0:18:47capable of smelling food from 20 miles away,
0:18:47 > 0:18:50and able to run as fast as a racehorse,
0:18:50 > 0:18:54this is an animal to be taken very seriously indeed.
0:18:54 > 0:18:57Their entire life is lived out in these brutal conditions.
0:18:57 > 0:19:00They absolutely thrive here.
0:19:00 > 0:19:02For us, it's a different story.
0:19:04 > 0:19:09Filming out here in the Arctic tundra is obviously very difficult,
0:19:09 > 0:19:15purely because every second of the day, cold dominates everything.
0:19:15 > 0:19:20I mean, if you allow your fingertips to be exposed to the cold
0:19:20 > 0:19:22for even a few seconds,
0:19:22 > 0:19:25then you're going to get frost nip and eventually frostbite.
0:19:25 > 0:19:28But there are other things that you don't think about,
0:19:28 > 0:19:30to do with the filming, that are really important.
0:19:32 > 0:19:36It's easy for us in the Arctic to warm up, we can put on layers.
0:19:36 > 0:19:39The trouble with the camera equipment is it's all metal.
0:19:39 > 0:19:43And metal plus minus temperatures is very bad.
0:19:43 > 0:19:47And even the cables start to freeze and cables can snap.
0:19:47 > 0:19:50The batteries, they drop their power very quickly,
0:19:50 > 0:19:52you've got to keep the batteries warm.
0:19:52 > 0:19:55The camera itself has a big jacket, just to keep it warm.
0:19:55 > 0:19:57You've got lots of heat packs.
0:19:57 > 0:20:01There's a lot of potential for things to go wrong in this temperature,
0:20:01 > 0:20:04and, yeah, it's a bit of a struggle sometimes.
0:20:04 > 0:20:06I'm absolutely loving it, yeah!
0:20:06 > 0:20:07It's great, really cold.
0:20:07 > 0:20:11It gets hard to talk cos your cheeks start freezing up!
0:20:11 > 0:20:15But, yeah, it's great fun to be here, great fun.
0:20:21 > 0:20:24Another animal with remarkable fur to protect it from the elements
0:20:24 > 0:20:26is the Arctic fox.
0:20:30 > 0:20:31Cute and cuddly...
0:20:31 > 0:20:34but tough as nails.
0:20:35 > 0:20:38And a visit from this rare wolverine
0:20:38 > 0:20:39did wonders for our morale.
0:20:39 > 0:20:41Go into infrared.
0:20:41 > 0:20:42We waited and waited.
0:20:42 > 0:20:47We even slept in the truck, and still no polar bears.
0:20:47 > 0:20:52Sometimes on wildlife stakeouts, you need a lot of patience and time,
0:20:52 > 0:20:55but we'll be back tomorrow.
0:20:55 > 0:20:59Out there in the darkness somewhere, is the animal we're looking for.
0:21:03 > 0:21:06So have I made myself an igloo out on the frozen tundra?
0:21:06 > 0:21:09Well, er, no.
0:21:09 > 0:21:11Actually, I'm staying in the town of Kaktovik.
0:21:11 > 0:21:16It's a tiny frontier town with 293 people, 43 huskies,
0:21:16 > 0:21:20and, every once in a while, a visiting polar bear.
0:21:20 > 0:21:23We just need to wait and watch.
0:21:24 > 0:21:28But, when our faces are frozen and we need to warm our toes,
0:21:28 > 0:21:30this is where we hide out.
0:21:35 > 0:21:38Right, get the snow off my shoes,
0:21:38 > 0:21:41give you a little tour around where we've been staying.
0:21:41 > 0:21:43This is the Waldo Arms, come and have a look.
0:21:43 > 0:21:46This is where we crash out, watch the telly.
0:21:46 > 0:21:49This is Jake, he's been cooking all our meals for us.
0:21:49 > 0:21:51Fish and chips.
0:21:53 > 0:21:54This is the dining room.
0:21:54 > 0:21:57This is where I sit down and I compose all of my music.
0:21:57 > 0:21:58I'm not going to do it now.
0:21:58 > 0:22:00Rosie, our director.
0:22:00 > 0:22:02A little telescope we've got so we can look outside
0:22:02 > 0:22:06and see if there's any bears coming in close to the town. At the moment,
0:22:06 > 0:22:09despite the fact it's nearly nine o'clock in the morning,
0:22:09 > 0:22:10it's still dark.
0:22:10 > 0:22:13Lots of pictures of polar bears.
0:22:13 > 0:22:17It's pretty much the closest we've come to any of those!
0:22:17 > 0:22:21Oh, you've got to see this, come down here. These are the bedrooms.
0:22:21 > 0:22:24This is where Nick and Johnny have been staying.
0:22:26 > 0:22:29As you can see, they are absolute slobs.
0:22:29 > 0:22:32Keep going back, keep going back.
0:22:32 > 0:22:33All right, come this way.
0:22:35 > 0:22:36And...
0:22:38 > 0:22:41..this is where I stay. So, er, yeah.
0:22:43 > 0:22:46Bathrooms.
0:22:46 > 0:22:48And this is the toilet.
0:22:48 > 0:22:52So you can't come in here.
0:23:00 > 0:23:01Morning.
0:23:01 > 0:23:04This is where we're staying.
0:23:04 > 0:23:08All right, I think the team's getting ready
0:23:08 > 0:23:10for a day of filming out in the freezing cold.
0:23:10 > 0:23:14This is Rosie, she's our director.
0:23:14 > 0:23:17Rosie, talk us through all the stuff you've got to keep yourself warm.
0:23:17 > 0:23:22- Well, I've got absolutely enormous mitts, liner gloves.- Right.
0:23:22 > 0:23:25- Every time I take these off, my fingers freeze.- Uh-huh.
0:23:25 > 0:23:29What about these enormous boots? Let's have a look.
0:23:29 > 0:23:31They've got a massive layer of padding inside,
0:23:31 > 0:23:35- and I've got three pairs of socks inside that.- All right.
0:23:35 > 0:23:37Here's Nick, the sound man.
0:23:37 > 0:23:40This is obviously to keep the microphone warm.
0:23:40 > 0:23:44- It's to keep my ears warm!- Yeah!
0:23:44 > 0:23:46And last, Johnny.
0:23:46 > 0:23:49You can see that the camera here is covered
0:23:49 > 0:23:52in this great big thick jacket to keep it warm.
0:23:52 > 0:23:55What else have you had to do to film in these temperatures?
0:23:55 > 0:23:58I've got lovely gloves inside here to keep my hands warm on the lens.
0:23:58 > 0:24:02The batteries suffer in the cold, so they've all got heat packs on them.
0:24:02 > 0:24:05Yeah, so if the battery gets freezing cold, it runs out of power?
0:24:05 > 0:24:07It runs out of power quickly.
0:24:07 > 0:24:10So you see, everyone here is really struggling
0:24:10 > 0:24:12to make sure that we can film all this.
0:24:12 > 0:24:16We are looking for one of the most dangerous predators in the world.
0:24:16 > 0:24:20So it's really important that we take things really seriously.
0:24:30 > 0:24:33OK, enough horsing around, let's go and find some bears.
0:24:36 > 0:24:38Despite the snow down the back of the neck,
0:24:38 > 0:24:41we're kitted out and as comfortable as we can be.
0:24:41 > 0:24:43We've protected the cameras as much as possible.
0:24:43 > 0:24:46All we need to do now is find a polar bear.
0:24:46 > 0:24:48Rarrr!
0:24:52 > 0:24:55We're heading right out to the brink of the frozen seas.
0:24:55 > 0:24:58And there's only one vehicle that can take us.
0:24:59 > 0:25:02Time to fire up Skidoos.
0:25:03 > 0:25:05Look at these!
0:25:05 > 0:25:08Finally, after four days of searching,
0:25:08 > 0:25:12we find the much-needed signs that we're on the right track.
0:25:14 > 0:25:17Polar bear tracks! Look at the size of them.
0:25:17 > 0:25:21It's really something to think that we're sharing the ice
0:25:21 > 0:25:24with one of the world's most terrifying predators.
0:25:26 > 0:25:29All the hard work and the cold is forgotten
0:25:29 > 0:25:32as we get our first glimpse of a polar bear.
0:25:34 > 0:25:36There's something out there.
0:25:37 > 0:25:40It's a bear. No more than 150 metres off from the shore.
0:25:40 > 0:25:45It's so exciting. I can just feel my heart start beating.
0:25:45 > 0:25:49So out there, about a mile off in the distance,
0:25:49 > 0:25:51is our first polar bear.
0:25:52 > 0:25:56He's just sort of ambling about at the moment.
0:25:58 > 0:26:02What a magnificent creature.
0:26:03 > 0:26:06Even a mile away from us, he'd scented us on the air.
0:26:06 > 0:26:09And shuffled off into the distance.
0:26:15 > 0:26:19The weather's had a turn for the worse.
0:26:19 > 0:26:23Unfortunately, the seas now have really started to freeze over,
0:26:23 > 0:26:27and it seems the polar bears have started to move off across the ice.
0:26:27 > 0:26:32So I think our chances of getting closer to a bear
0:26:32 > 0:26:33are pretty much done.
0:26:33 > 0:26:39That said, any animal that can live and hunt in conditions like this,
0:26:39 > 0:26:41and be completely comfortable,
0:26:41 > 0:26:45is a pretty powerful creature, and has to go on the Deadly 60.
0:26:48 > 0:26:51Our encounter with the undisputed king of this icy land
0:26:51 > 0:26:54was one we'll never forget.
0:27:00 > 0:27:02So that is how Deadly 60 is made.
0:27:02 > 0:27:06We've braved crippling cold that freezes your eyeballs,
0:27:06 > 0:27:09and the sticky sweatiness of the darkest jungles,
0:27:09 > 0:27:13to bring you footage of the world's wildest animals.
0:27:13 > 0:27:15But I have to admit...
0:27:15 > 0:27:17it is quite a lot of fun!
0:27:25 > 0:27:28My sandwich is frozen solid!
0:27:28 > 0:27:31Separated at birth - Rich the sound man and a piranha.
0:27:31 > 0:27:34Show us your teeth, Rich.
0:27:36 > 0:27:37Ah, ow!
0:27:37 > 0:27:41Join us next time for more incredible animal encounters
0:27:41 > 0:27:43on Deadly 60.
0:27:44 > 0:27:49Look at that, absolutely amazing.
