Sony Pictures has surprising plans for its “Jump Street” and “Men in Black” franchises: Combining them.

E-mails from the studio’s motion picture chief Amy Pascal leaked onto the Internet this week by hackers reveal that a follow-up to this year’s comedy hit “22 Jump Street” will have cops played by Jonah Hill and Channing Tatum interacting with the universe of the sci-comedy franchise “Men in Black,” which previously starred Will Smith and Tommy Lee Jones.

Details on the movie are scarce, but the e-mails do indicate Messrs. Smith and Jones would not be included in the movie, at least in prominent roles. Phil Lord and Chris Miller, who directed the last two “Jump Street” films, are producing the picture and may direct it.

In an e-mail to Ms. Pascal, Mr. Hill says “jump street merging with mib i think that’s clean and rad and powerful.”

In another e-mail, Hannah Minghella, a president of production for Sony’s Columbia Pictures label, says of the joint sequel, “We don’t have a script yet so we’ll be greenlighting the movie off the concept and the talent involved.”
