0:00:12 > 0:00:15Hello, I'm Robert Webb.
0:00:15 > 0:00:18Welcome to Great TV Mistakes.
0:00:18 > 0:00:22Now, I know what you're saying - "But people in telly don't make mistakes.
0:00:22 > 0:00:24"They're all perfect, like you, Rob."
0:00:24 > 0:00:26Not true. Everyone makes mistakes.
0:00:26 > 0:00:29You just called me Rob, for instance.
0:00:29 > 0:00:33And no-one but no-one calls me Rob unless I give them permission. Understand?!
0:00:33 > 0:00:36Don't worry. People in telly are just like you.
0:00:36 > 0:00:40They mess up. A crew member appears in the back of shot, a prop changes colour,
0:00:40 > 0:00:43someone commissions another series of My Family.
0:00:43 > 0:00:45Mistakes get made, and that's where we come in.
0:00:45 > 0:00:49We find these embarrassing errors and make a show out of them.
0:00:49 > 0:00:52Some people might call that schadenfreude. I just call it funny.
0:00:52 > 0:00:54Enjoy.
0:00:56 > 0:01:01This is X-Files rain, heavy and persistent, like Mulder,
0:01:01 > 0:01:03apart for the heavy bit.
0:01:03 > 0:01:08Dana and Fox are in hot pursuit of a woman doing some top-notch driving-in-heavy-rain acting.
0:01:11 > 0:01:14Moving the steering wheel about, frowning at rain...
0:01:14 > 0:01:17and then she hits a cloudy ghost. Bosh!
0:01:21 > 0:01:26But when Mulder and Scully pull over seconds later, all the rain has gone. Spooky.
0:01:26 > 0:01:31# Da-da-da-doo, da-da-da-doo... # Sorry, that's The Twilight Zone, sorry.
0:01:31 > 0:01:33- I can see her.- Michelle!- Help!
0:01:38 > 0:01:40A high-speed chase
0:01:40 > 0:01:42in Knight Rider and Michael is in pursuit
0:01:42 > 0:01:44of two blokes who have kidnapped a lady.
0:01:44 > 0:01:46Oh, she's a terrible back-seat driver.
0:01:46 > 0:01:48That car is all over the shop.
0:01:48 > 0:01:51Three drivers, one steering wheel, that's asking for trouble.
0:01:53 > 0:01:56Oh, no, no, no, no, leave it.
0:01:56 > 0:01:59Sit down, you silly cow! Oh, too late, she's jumped.
0:01:59 > 0:02:01Well, somebody did.
0:02:01 > 0:02:05- Crazy broad jumped out!- I'm afraid that was your unconscious female.
0:02:05 > 0:02:08No it wasn't, KITT, you're talking out of your tailpipe.
0:02:08 > 0:02:12That's her stunt double in an ill-fitting blonde wig.
0:02:12 > 0:02:16She's less lookalike and more look nothing like.
0:02:18 > 0:02:21A clip from classic Dr Who episode Genesis Of The Daleks,
0:02:21 > 0:02:25and keep your eyes on the Dalek chatting with Davros
0:02:25 > 0:02:27and the light bulb flashing on his head.
0:02:27 > 0:02:31That's how deaf people know that a Dalek is talking, by the way, it's a courtesy thing.
0:02:31 > 0:02:34Hold on a sec, his light's gone out.
0:02:34 > 0:02:37Maybe he forgot to pay the Da-lecky bill.
0:02:37 > 0:02:41But then, between takes, while Davros practises his shouting...
0:02:41 > 0:02:44You will obey me!
0:02:44 > 0:02:48..there's a chance to unscrew the bulb and pop a new one in.
0:02:48 > 0:02:50We are the superior beings.
0:02:50 > 0:02:54On with the serious business of mass extermination and sink plunging.
0:02:54 > 0:02:56Exterminate!
0:03:00 > 0:03:03The Doctor again, and this is what I call thrilling stuff.
0:03:03 > 0:03:06There again, I'm quite easily thrilled.
0:03:06 > 0:03:08Oh, look, the Doctor is climbing up that giant television aerial,
0:03:08 > 0:03:12trying to stop Maureen Lipman being transmitted.
0:03:12 > 0:03:16You cannot stop the wire. Soon I shall become...
0:03:16 > 0:03:20Then, as Dave's a-dangling from the pylon, his foot suddenly disappears.
0:03:23 > 0:03:25Here it is, here it isn't.
0:03:25 > 0:03:29Yes, the BBC's blue screen is no larger than a tea towel.
0:03:33 > 0:03:37A thrilling FX scene from Blake's 7,
0:03:37 > 0:03:41the doddery senile granddad of the TV sci-fi family.
0:03:41 > 0:03:45Once again, the audience at home are on the edge of their seats, getting up to leave the room.
0:03:45 > 0:03:49But gasp as the bad guy is sucked into space.
0:03:49 > 0:03:54Although, he's not so much being sucked as dangled by that highly visible safety harness.
0:03:54 > 0:03:56Wheeee!
0:03:58 > 0:04:02TV shows are a huge investment of time, money and effort,
0:04:02 > 0:04:05but you can spend months and months getting something right,
0:04:05 > 0:04:09hiring the very best actors, camera persons, writers and crew,
0:04:09 > 0:04:14only to have the whole thing ruined by some extra in the background being a tit.
0:04:14 > 0:04:18These people are a menace, wandering in and out of the back of every shot,
0:04:18 > 0:04:22trying to be ordinary members of the public, who are the only things worse than extras.
0:04:22 > 0:04:26Nothing causes more trouble on set than members of the public.
0:04:26 > 0:04:30I hate them all. Apart from you, obviously.
0:04:33 > 0:04:36Some classic muscle Mary slow mo running now from legendary
0:04:36 > 0:04:39beachfront twaddle merchants Baywatch.
0:04:39 > 0:04:43See their toned torsos as they pound along the sand,
0:04:43 > 0:04:46see their hair blown by the gentle Pacific breeze,
0:04:46 > 0:04:49see the kid in the background pulling a moonie.
0:04:49 > 0:04:51That's worth a second look.
0:04:53 > 0:04:55Everyone's a critic.
0:04:57 > 0:04:59You don't even have to. I'm sure you were pretty freaked out.
0:04:59 > 0:05:01Totally.
0:05:01 > 0:05:03See this woman with the tartan top?
0:05:03 > 0:05:06Now remember her, cos this lady is about to take the art
0:05:06 > 0:05:10of the attention-seeking TV extra to a whole new dimension.
0:05:10 > 0:05:15This is Buffy's high school, of course, and she is presumably the most mature student.
0:05:15 > 0:05:17I...think you're the coolest.
0:05:17 > 0:05:21There she is again, drawing attention to herself with that big red bag.
0:05:21 > 0:05:26Now, spin on. And there she is again, walking in the opposite direction.
0:05:26 > 0:05:29No, she's not. She's over there, walking up some stairs,
0:05:29 > 0:05:33drawing attention to herself just like those extras aren't supposed to.
0:05:33 > 0:05:37Back for more stair climbing, this time without the bag. Clever.
0:05:37 > 0:05:39Still going up the stairs.
0:05:39 > 0:05:42Mind you, at least we know where she is. No we don't.
0:05:42 > 0:05:45Buffy, now she's behind you.
0:05:45 > 0:05:50"Right, I've had enough of this," said the director, "Get that woman out of my sight.
0:05:50 > 0:05:54"Nobody lets her back on this set."
0:05:54 > 0:05:55Whoa, how did that happen?
0:05:55 > 0:06:00Crafty cow, she's taken off her horrible tartan jacket and given the red bag to someone else.
0:06:00 > 0:06:04Damn you, nightmare tartan extra lady!
0:06:04 > 0:06:09Still, the jacket's gone, the bag's gone, and, finally, so is she.
0:06:09 > 0:06:10Or not.
0:06:12 > 0:06:17Sex And The City, a show about four single young women.
0:06:17 > 0:06:20Well, three young women and the one who plays Samantha.
0:06:20 > 0:06:25But let's rewind and look at those two extras on the left of picture sitting side by side.
0:06:25 > 0:06:30Now, spin on and clearly one of them has dropped a massive guff
0:06:30 > 0:06:35because next time we see them, they're sitting miles away from each other in separate rows.
0:06:35 > 0:06:39Poor Sam. Must have been a pretty serious guff. Someone open a window!
0:06:41 > 0:06:47The X-Files, and Scully has a mysterious dead body to investigate.
0:06:47 > 0:06:53In this case, the mystery is why they chose the most fidgety man in North America to play the corpse.
0:06:53 > 0:06:57See how the faintest prod from Scully makes the big wuss blink.
0:06:57 > 0:07:01Not so much dead man's body, more big girl's blouse.
0:07:01 > 0:07:05But just in case anyone missed that, moments later,
0:07:05 > 0:07:10he leaves everyone at home in no doubt that this is just acting as Scully unwisely decides to
0:07:10 > 0:07:16balance this heavy plastic ruler on his tummy-wummy. "Ow, it's cold!"
0:07:16 > 0:07:17We've got a breather!
0:07:21 > 0:07:23I love Lost. It's top-notch
0:07:23 > 0:07:27allegorical surrealist drama with a satirical subtext.
0:07:27 > 0:07:30Plus, it's got that funny fat bloke with a beard in it.
0:07:30 > 0:07:33Yeah, he's got boobs like a lady.
0:07:33 > 0:07:38In fact, the only problem with this show is that it makes no sense.
0:07:38 > 0:07:40That, and their decision to use an extra with chronic asthma
0:07:40 > 0:07:43to play a corpse and then put him in the front of shot.
0:07:43 > 0:07:44Just look at this.
0:07:44 > 0:07:47ROBERT BREATHES HEAVILY
0:07:52 > 0:07:56Mind you, that fat bloke's funny. Oh, dear...
0:07:58 > 0:08:00I mean, dogs can find pot and bombs so...
0:08:00 > 0:08:05Time for more weird goings on in Lost, and look out for the lovely
0:08:05 > 0:08:07couple walking past in the background. There they go.
0:08:07 > 0:08:09Probably off to catch some fish.
0:08:09 > 0:08:11Wish they'd walk past again. Oh, lovely.
0:08:11 > 0:08:16That's the trouble with being marooned on a desert island, nothing to do but walk round in circles.
0:08:18 > 0:08:21Thanks to all our contributors for being so sloppy.
0:08:21 > 0:08:24It's a good job it's telly and nothing more important
0:08:24 > 0:08:28like a paper round, otherwise you'd have been fired. Bye-bye!
