It's like being good looking wasn't enough. Dude must get so.much.pussy. Or maybe he's a one pussy sorta dude.
I'm pretty sure The Notebook gave him a lifetime pass in that regard.
I often find that watching a British movie can be refreshing or frusterating, it can be enough like an American film that everything makes perfect sense, but a funhouse mirror version of familiar things show up onscreen.
Attack the Block is so much and so little like a typically American alien invasion flick.
The recent American made low-budget "creatures invade an apartment complex" film Skyline was about a bunch of callow, rich, pretty people dodging shiny CGI monsters and bickering with each other about nothing important at all, PG-13 and dumb as hell. Attack the Block is about a bunch of apparently very delicious slum kids/small time hooliagans who all talk like Ali-G, dodging a bunch of "wolf-gorilla-fuckers" that are clearly men in suits (still looks awesome) and engage in some not overbearing social critique whilst doing so, a strong R rating and funny and smart.
Its this familiarity of story (another aliens attacking movie) and bracing freshness of the context it takes (vs. disaffected and way underprivlidged youth) that gives the tropes on hand the effectiveness they have here. At its most basic its a very fun monster movie with a palpable sense of danger and a nice humourous streak in between. Its very fine entertainment that also just happens to be more substantial than most films that also have monsters with bloodstained teeth in them.
4/5
