"She just brings an intelligence and a complexity and a charm to her character and onscreen," gushes Tom of his blonde co-star, who he likens to Grace Kelly or Faye Dunaway. "I had such a great time acting with her."

"What developed was a really great sort of professional rapport between these two characters who, in any other universe, would have been romantically involved," explains writer/director Christopher McQuarrie. "But because of who they are and because of the lives they've chosen, they never can be, and we didn't want that to overwhelm the story."

Fans of the book series all know that Jack Reacher likes his coffee; a blue-collar diner sets the scene for this behind-the-scenes clip. Among the cool details in the exclusive video, check out the camera slate that reads One Shot, which was the original title of the film before it was changed to Jack Reacher. One Shot is the ninth book in the bestselling Reacher series and is based on the military snipers' creed: "One shot, one kill."
