One of the seminal Not Ready for Primetime Players from NBC’s "Saturday Night Live" has joined the HBO production "Behind the Candelabra," about the life of Liberace, reports Zap2It.com, citing a piece in Variety.

Dan Aykroyd, who was a mainstay on “SNL” during its first four seasons — from 1975 to 1979 — will play Seymour Heller, Liberace’s manager.

The production, set to begin filming this summer, stars Michael Douglas as the famed pianist and Matt Damon as his live-in lover, Scott Thorson.

The script is based on Thorson’s memoir "My Life With Liberace." Aykroyd’s character, Heller, was was not supportive of Liberace’s relationship with Thorson.

The movie will be directed by Oscar winner Steven Soderbergh ("Ocean’s 11"), with Richard LaGravenese ("The Mirror Has Two Faces") writing the screenplay. Gregory Jacobs and Susan Ekins are producing with Jerry Weintraub as executive producer.

"Behind the Candelabra" was set to be a Warner Bros. theatrical release, but will now take a different route. It will debut on HBO as a TV movie and then hit theaters outside the U.S. and Canada as a big-screen release.

HBO Enterprises will sell the film to independent distributors.
