Williams will play Huey Jarvis, a legendary music mogul and mentor to Lucious Lyon. Jarvis hosts a prestigious series of weekly “Living Room” shows, an appearance on which greatly boosts an artist’s chances of winning music’s top awards.

Williams is a well-known character actor with a career dating back to the 1960’s. He famously played Linc Hayes on the 1970’s TV series “The Mod Squad.” He also previously collaborated with “Empire” co-creator Lee Daniels on the 2013 movie “The Butler.”
