In an interview with MTV News, "Star Trek" rebooter J.J. Abrams said that he would not return to direct the fourth "Mission" Impossible" movie."I'm producing with Tom," he said recently. "My guess is, given other things, that I will not be directing the movie."Abrams didn't really address rumors claiming that Tom Cruise would not star in this new chapter, but here are a few more things he did say:"I don't want to give anything away yet, but I will say that it's a story that will feel consistent with the world that has been created," he explained.
