Warner Bros. General Counsel John Rogovin has resigned his post, following the completion of parent company WarnerMedia $43 billion merger with Discovery.

Rogovin had been at the helm 14 years. Variety, which first reported his departure, credited him for masterfully handling the IP of some of the company’s biggest properties, including “The Hobbit,” “The Lord of the Rings” and “Two and a Half Men.” It also said he rescued the film group from a high-stakes rights battle over the character of Superman, brought on by comic co-creator Joe Shuster’s family.
