Tom Cruise is being replaced in the small-screen adaptation of Jack Reacher because he's 5'7". In the books on which the films are based, Reacher is described as a 6'5" man with "hands the size of dinner plates." British author Lee Child revealed in a recent radio interview that many readers complained that Cruise was cast in the film. "I really enjoyed working with Cruise. He's a really, really nice guy. We had a lot of fun. But ultimately the readers are right," Child admitted. "The size of Reacher is really, really important and it's a big component of who he is." He continued, "The idea is that when Reacher walks into a room, you're all a little nervous just for that first minute. And Cruise, for all his talent, didn't have that physicality."
