During a presentation at the movie industry’s annual ShoWest convention in Las Vegas on Wednesday, Sony distribution president Rory Bruer said that the studio is going back for thirds on the Ghostbusters and Men in Black franchises. Now, of course, the question on everyone’s mind is: Who will be starring in said monster-fighting movies? Sony isn’t talking (Bruer’s announcement arrived almost in passing), but it is expected that Ivan Reitman, Harold Ramis, Bill Murray, and Dan Aykroyd will return to be involved to some degree on a followup to 1989’s Ghostbusters II. The story is being written by Office scribes Gene Stupnitsky and Lee Eisenberg, and it will focus on a new crew of Ghostbusters who are mentored by the veteran fighters. (Contrary to Internet buzz, Judd Apatow is not on board to produce.) Meanwhile, Men in Black III is in even more of a nascent stage. Sony won’t comment on whether Will Smith will be involved in the project in any way, either as an actor or producer. There is said to be interest in one screenwriter for the job, but he has not yet been hired.
