It had been speculated that a sequel to Jack Reacher would only be possible if the film did well overseas -- and it did. And apparently Paramount and Skydance are already working out some sequel details.
There have been reports that Reacher might be a one off. The movie cost $60 million and I am hearing that they are already figuring out the sequel at Paramount and Skydance. Studios are all about franchise building, and some take off financially on the second go-around. There are so many good Reacher books written by Child that there’s a wealth of ground to cover here.Source: Deadline
