William Earl WME veterans Christian Muirhead and Richard Weitz have been promoted to co-chairmen of the powerful talent agency that is a cornerstone of Endeavor. The pair will succeed Lloyd Braun, who will step down from the WME chairman role at year’s end. “The appointment of Richard and Christian marks a truly transformative day for WME, which continues to be the inspirational core of Endeavor,” said Endeavor president Mark Shapiro. “I’ve seen first-hand their innate ability to lead, to build meaningful relationships, and to leverage the broader Endeavor network in service to our clients’ aspirations. Coupled with their deep understanding of the entertainment landscape, I can say with certainty that there are no better or more complementary individuals to now lead the agency.”
