Daniel Radcliffe shaves his head to play a neo-Nazi

Daniel Radcliffe has unveiled a dramatic new look for his movie Imperium. The Harry Potter star will play an undercover FBI agent who infiltrates a group of neo-Nazis trying to build a dirty bomb in the upcoming thriller. Radcliffe chose his Google+ page to premiere the image, telling fans: "Here's the first look of me as FBI agent Nate Foster in Imperium. "We began filming the movie this week. I'm very excited about it and will tell you more about it soon!" Imperium is based on the experiences of ex-FBI agent Michael German, who co-wrote the film with director Daniel Ragussis. After a decade sporting a haircut you could set your watch by in Harry Potter, Radcliffe will wear flowing locks for Victor Frankenstein in December this year.
