FEARnet's Angie Greenup chats with writer-director Joe Cornish and actor John Boyega at Comic-Con 2011 about how their acclaimed sci-fi thriller Attack the Block is a throwback to the great alien invasion films of yesteryear. In theaters on July 29, 2011.Attack the Block is a fast, funny, frightening action adventure movie that pits a teen gang against an invasion of savage alien monsters. It turns a London housing estate into a sci-fi playground. A tower block into a fortress under siege. And teenage street kids into heroes. It's inner city versus outer space.
