Actor Ben Barnes (The Chronicles of Narnia, Dorian Gray, Stardust) and director Nick Hamm (Godsend, The Hole) discuss their new film, Killing Bono -- a comedy about two Irish brothers struggling to forge their path through the 1980's music scene whilst the meteoric rise to fame of their old school pals U2 only serves to cast them deeper in to the shadows. Moderated by Chris Hewitt from Empire magazine.
