Lee Child is the author of a series of books featuring Jack Reacher, an ex-MP who is 6'6" tall and weighs either 230 or 260 pounds. Either way, this is one big guy. His size plays an important part of the character's persona. One of Mr. Child's books has been made into a movie that is scheduled for release this coming December.
Tom Cruise has the role of Reacher, all 5'7" of him. Some may think of him as a gifted actor, but I think he's going to have to be a GREAT actor to make me believe he is 6'6".
