THE FACTS

On July 7, 2005 four men strapped explosives to their bodies, walked into the heart of London's transport network and blew themselves up. Fifty-two people were killed, in addition to the bombers - three weeks later, four more men tried to do the same.

None of them were mercenaries or émigrés sent from abroad. No one spotted them, they didn't stand out. They were born, brought up and educated in Britain - Manchester United supporting, iPod owning, dress-like-us, speak-like-us people. They were Brits.

Britz explores how a young intelligent British Muslim could feel so disenfranchised, so powerless and become so angry at their country of birth that they would commit an extreme and despicable act and ultimately it asks how we can ever hope to prevent such an incident re-occurring.

The idea for the films, according to Peter Kosminsky, started with the July 7 bombings. Kosminsky considered telling the personal stories of the July 7 bombers, in the way he had told the story of government scientist David Kelly in The Government Inspector. But in light of his own experience as a second-generation immigrant, he wanted to look more generally at second-generation Muslim disillusionment with Britain (domestic and foreign policy in particular.) "I decided, in discussion with my colleagues, that the best thing was to fictionalize it - to research the way Muslims think and feel at the moment - and then try to create some fictional characters drawing on what we'd learned."
