John C. Reilly will replace Michael Shannon in the role of Jerry Buss for an untitled HBO project about the 1980s Los Angeles Lakers.

The show is based on Jeff Pearlman's non-fiction book Showtime: Magic, Kareem, Riley, and the Los Angeles Lakers Dynasty of the 1980s that chronicled the team that won five NBA titles in the decade.

Adam McKay is set to direct the pilot, with Jason Clarke playing Jerry West. 

Shannon exited the role due to creative differences.
