A spokesperson for the studio confirmed the move last night  after the veteran executive informed co-chairmen and co-CEOs Gary Barber and Roger Birnbaum of his decision.
According to trade reports, Vollman had grown frustrated over the lack of direct input on the MGM slate, given that co-finance partners on major titles like The Hobbit and Bond 23 would take the lead on marketing and distribution.
A statement issued by Barber and Birnbaum read: “Michael Vollman is a great executive. We could not have gotten through this enormous transition over the past 7 months without his clarity, his guidance and his commitment. We love him and while his contract is ending, we are confident that our paths will cross again.”
Vollman joined MGM in 2008 after serving as vp of integrated marketing and theatrical publicity at Paramount.
Prior to Paramount he spent a decade at DreamWorks overseeing field marketing, internet marketing and media promotions and before that he served as marketing manager at Buena Vista Pictures.
