Harry Potter might be a movie murderer. Daniel Radcliffe, who played the teen wizard in the eight-film series, has moved on to very different roles since his time at Hogwarts ended. His upcoming film, Horns, sees him adopting an American accent and being accused of killing his girlfriend. The movies latest trailer aired first at Comic-Con, and opens with Radcliffe in happier times, before shifting to show him trying to cope as bony appendages grow out of his head and his life falls apart.
