Karl Hungus had it already in his top-movies-of-2011-list, very funny movie about aliens attacking a a highrise in London and the stoned up-to-no-good-homeys defending their block.

Yo bum rush the show! My roommate was telling me about this. He's so far ahead of the curve, he actually travels into the future to see movies before they even get filmed. Looks a lot more professional than I was expecting. And I'm a sucker for loveable young British thugs.
