It's difficult to judge a comedy movie on its trailer as they aren't always representative. Something that looks hilarious in a two minute teaser often turns out to be the very opposite of that; you realise that, hey, the studio used up all the good jokes in the trailer. Grimsby has a good idea at its core, but looking at its official trailer, it's difficult to work out whether or not it'll actually be any good. Starring Mark Strong as a secret agent and Sasha Baron Cohen as his football hooligan brother, the situation is ripe for comedy - and yet in the two minutes and twenty three seconds the trailer has to sell you the movie, it's hard to work out whether it's a dud or all the best jokes have been saved for the final film. Sasha Baron Cohen has struggled to live up to the promise of his earlier films, Borat and Bruno, so there's no real reason to suspect this will be anything special. There's one scene in the trailer where he gives Mark Strong a wedgie, so, you know... start worrying.
