Daniel Radcliffe continues to move away from his Harry Potter roots with the story of an FBI agent sent undercover to infiltrate a white supremacist group suspected of planning a terrorist attack. With impressive supporting turns from True Blood’s Sam Trammell and the always excellent Toni Collette, Imperium is a watchable and thought-provoking drama, desperately trying to ask questions without ever being as tense or shocking as it aims to be. It’s decent viewing, but memorable only for its lead. While unconvincing at first, Radcliffe grows into the role, becoming better and better the longer it goes on. It’s an admirable effort from the immensely likeable star.
