"Mr. Child's background in television led him to develop some theories about what was happening. One is that Hollywood storytelling typically relies on character arcs in which the hero faces a number of moral dilemmas so he can change and grow.

Reacher is the opposite of that, Mr. Child says. 'His appeal is that he does not change one iota. He's the same at the end of a novel as he was at the beginning, and he doesn't learn anything either, because he knew it all to start with.'"

I love Reacher, but Tom Cruise??  Reacher is 6 feet 5 inches, 250 pounds; Cruise is what? 4 feet 9 inches, 150 pounds?
