Executive producer Adam McKay is directing the pilot, which chronicles the professional and personal lives of the 1980s Lakers, one of sports’ most revered and dominant dynasties — a team that defined its era both on and off the court.

Gordon will play Linda Zafrani, whose intelligence and savvy have earned her a position in the Forum Office, but the arrival of new ownership—Jerry Buss and his ambitious daughter Jeanie—requires her to navigate a complicated web of personal and professional relationships.

Morgan will portray Earvin Johnson Sr. For decades, Earvin Johnson Sr. worked as both a garbage man and on an automobile assembly line to provide a better life for his children. When his son Earvin “Magic” Johnson is presented with an expensive NBA contract, the differences in how Earvin Sr. and his namesake handle privilege, opportunity and attention are made obvious.

Garrett is Chick Hearn, the legendary Lakers announcer who coined terms essential to basketball’s lexicon—including slam dunk, airball, and no-look pass. His colorful language and “world’s eye view” were so essential to fans he became one of the few personalities to lead simultaneous radio and TV broadcasts.

Bovill will play Donald Sterling, who already was notorious for his questionable hairstyle and stingy management of the Clippers—before the infamous tape of a sexist, racist rant went public. Reminiscent of another famous 80’s Donald, Sterling pursues the trappings of fame but lacks tact, empathy and grace.

Desouza is Michael Cooper. Despite having been drafted the season before, a devastating knee injury rendered Cooper a “rookie” alongside Magic Johnson. Anxious and unsure of himself, Cooper is nonetheless determined to prove his worth to the team.

Also joining the cast is Joey Brooks, who plays Lon Rosen, an ambitious but overlooked intern at Forum Offices. Rosen works his way up to an executive position, eventually becoming Magic Johnson’s manager and closest confidante.

They join previously announced cast members Jason Clarke (Jerry West), John C. Reilly (Jerry Buss), Quincy Isaiah (Magic Johnson), Solomon Hughes (Kareem Abdul-Jabbar) and DeVaughn Nixon (Norm Nixon).
