Two much-talked about films debut at the Sundance Film Festival this week. Four Lions, a feature film debut from Chris Morris is a comedy about a band of wannabe terrorists, from the North of England. Morris has said he hopes it will do for Islamist extremists what Dad's Army did for Nazis – making them look "scary but also ridiculous".
Morris is not one to shy away from sensitive subjects. His Brass Eye show "Paedogeddon" tackled Paedophilia and the associated moral panic prevalent in parts of the British media at the time.
Also, Exit Through the Gift Shop, a film by British artist Banksy , is billed as the "the world's first street art disaster movie".
