There's a new "Ghostbusters" movie in the works, and, no, I'm talking about writer/director Paul Feig's all female remake that's hitting theaters next summer. What I'm talking about is the other Ghostbusters movie starring Christ Pratt and Channing Tatum that has been rumored (and denied) for a while.MTV caught up with writer Drew Pearce at the New York premiere of "Mission: Impossible - Rogue Nation," and asked him if the rumors of his involvement in a second "Ghostbusters" movie are true." 'I’ve finished my work on that in the last couple weeks,' Pearce said.
