The media company Lionsgate has quietly brought aboard a new general counsel, Bruce Tobey, who spent the past decade as a partner at O’Melveny & Myers and before that was chief operating officer of CBS Films and executive vice president at Paramount Pictures.

Tobey’s arrival at Santa Monica, California-based Lionsgate comes as the company plots a historic restructuring that will split its two businesses—the TV and movie studio Lionsgate and the Starz streaming service—into separate, publicly traded companies. The split-off, percolating since last year, is scheduled to occur in September.
