Jack Reacher's size is part of the plot in many of the books. Cruise could play a sneaky, assassin type character, but a bad-ass bruiser of a man??? They're going to have to use some of that reverse hobbit filmography.
I'll probably watch it, but I've never really had a problem separating movies from their literary counterparts.
