MGM marketing chief Michael Vollman is leaving the Lion after three years.

MGM confirmed Monday that Vollman is departing from his slot as exec VP of theatrical marketing when his contract expires in mid-August.

“Michael Vollman is a great executive,” said co-chairmen and CEOs Gary Barber and Roger Birnbaum. “We could not have gotten through this enormous transition over the past seven 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 oversaw the release of “Valkyrie” in 2008, “Fame” in 2009 and “Hot Tub Time Machine” last year. MGM emerged from a pre-packaged bankruptcy in December under Barber and Birnbaum, and has cut staff by about 100 since then.

Most of MGM’s slate is co-financed, such as “The Zookeeper” and the upcoming James Bond pic, both which will be distributed by Sony.

New Line parent Warner Bros. reached a deal in January to handle worldwide distribution on “The Hobbit,” taking over most international distribution and homevideo on the two films from MGM in exchange for funding MGM’s half of the production costs. The “Hobbit” pics are aimed for release in December 2012 and December 2013.

Vollman previously worked for Paramount Pictures and at DreamWorks.
