The Four Lions writers on the dark side of comedy.

Chris Morris brilliant, controversy-baiting comedy Four Lions which follows the adventures of a group of hapless wannabe suicide bombers - opens this week, and we strongly recommend it, for its bold, brave and gut-bustingly funny. We sent Chris Hewitt along to the films UK premiere at the Bradford Film Festival recently, where he spoke to Morris, producer Mark Herbert, writers Jesse Armstrong and Sam Bain, and most of the Four Lions themselves.
