If you’re talking about the movie “Jack Reacher” know that the character in the books is 6’5” and weighs in at 240 or so. He is also NOT violent by nature rather a Paladin type character. Why TC has been cast is a wonderment. I’ll not watch the movie as Reacher exists in the theater of my mind.
It’s Hollywood.
The book describes a 6’5” character and they pick a midget with a pretty face.
