Last February, Landau recalled his first time working with Cameron when he was at Fox and assigned to the director's 1994 action comedy True Lies. "I think Jim was a little skeptical. He said, 'So I understand we're gonna get to be pretty good friends. Or maybe not,'" Landau told Deadline's Pete Hammond on Behind the Lens with a Laugh.
