Every channel needs filler, and there are only so many times you can repeat Family Guy (actually, best not tempt fate). That doesnt excuse the joyless Great Movie Mistakes, which has lingered on the margins of BBC Three like a pub quiz bore on a party cruise. Nobody wants it there, and nobody acknowledges it, but every once in a while you lock eyes, and realise that one day, thatll be you. The format is recession-bustingly simple. Bloopers from familiar Hollywood movies are played and a funny person narrates. The original funny person was Robert Webb, whose career has benefitted from a mysterious decree that he will always be in work, despite being Coldplays idea of a good comedian. More recently its been the sketch troupe Pappys, and the show now has a framing device that removes the sense it was cobbled together five minutes before airtime. Unfortunately, Pappys are Coldplays idea of a funny sketch troupe, but even George Carlin would struggle to wring laughs out of the changing direction of Nicolas Cages forelock. We all like spotting the occasional blooper- it makes us feel superior to people who earn our wage in thirty seconds- but Great Movie Mistakes sucks the fun dry. It tries to be a laugh, like that pub quiz bore after a few tequilasbut you still saw it sitting in the lifeboat, crying bitter tears because Taylor Lautners chinos go from crimson to maroon between shots. And thats something you never wanted to see.
