U.S. movie studio Metro Goldwyn Mayer is set to replace its chief executive, Gary Barber, five months after extending his contract for five years and has begun a search for a new CEO.

MGM has reportedly formed an office of the CEO to oversee operations and facilitate its strategic initiatives. The office will reportedly report directly to the board and include a group of divisional heads and senior executives as well.

The members of the temporary office will include former executives from Pixar, CBS, Viacom and Google Ventures.

MGM also stated last year that it would buy an 81% stake in U.S. channel Epix and Lionsgate Entertainment Corp LGFA.N for about $1 billion.
