Johnny Depp has joined the cast of Warner Bros. I Am Legend, next to Will Smith, according to Black Film. There’s no telling which role Depp will play, but given his penchant for playing extraordinary weird-like characters, expect a juicy plum part, like the neighbor, now one of the living dead. Set in Los Angeles after a biological war, the film centers on the sole healthy survivor, a man who finds himself in a battle against nocturnal mutants. Based on the novel by Richard Matheson, the film will be written by Mark Protosevich. Constantine director Francis Lawrence will helm the film with David Heyman, Akiva Goldsman, Neal Moritz and Erwin Stoff serving as producers. Shooting begins in September.
