Starz Media, the pay TV operation that recently sold its Overture Films unit, is selling its animation studio Film Roman to a group of investors lead by former Film Roman president Scott D Greenberg.

The terms of the deal, which is expected to close before the end of the year, were not disclosed.

Film Roman is best known for producing animation for the Fox Television and Gracie Films’ The Simpsons. It has also produced animation for Fox’s King of the Hill, MTV’s Beavis and Butt-Head and other series.

“Film Roman is unmatched in the quality and breadth of the traditional animation it creates, and with its recent successful move into CG animation, the studio is poised for even bigger growth,” Greenberg said in a statement. 

After he left Film Roman in 2008, Greenberg teamed with animation producers Mark McJimsey and Joel Kuwahara to co-found animation company Bento Box Entertainment. The new Film Roman investor group intends to buy Bento Box and combine the two production companies, under the management of Greenberg, McJimsey and Kuwahara.
