First, let me emphasize that this is not about the highly subjective question whether or not Tom Cruise should play Jack Reacher.
Lee Child's novel One Shot is being turned into a movie. Tom Cruise plays the main character, Jack Reacher. However, people knowing Reacher – a 6'5" giant – will understand why this has been (and is) a matter of fierce debate. But Lee Child approves of it, and, frankly, it's none of our business. So, case closed.
What I'm curious about, though, is whether there have been other serious candidates to play Jack Reacher and why they opted out or were found less suitable than Cruise.
I can read the facts, but this kind of background is interesting but hard to find.
