Actor Nick Frost (Shaun of the Dead, Hot Fuzz, Paul) and director Joe Cornish (of Adam & Joe) discuss their new film. Attack the Block is an action-adventure that pits a teen gang against an invasion of savage alien monsters. It's inner city versus outer space and the estate is about to become a battleground, with a bunch of kids about to become the block's only hope. Moderated by Edith Bowman at the Apple Store, Regent Street in London.
