In Daniel Radcliffe's continuing quest to make us all forget he ever played Harry Potter, he shaves his head and gets a Nazi tattoo in upcoming film Imperium. The movie finds him playing an FBI agent tasked with infiltrating a violent white supremacist group planning to commit terrorist acts to further its cause. The whole thing takes on an extra level of scary since it's based on the actual experiences of former FBI agent Mike German, who wrote the 2007 book Thinking Like a Terrorist.
