Legendary producer Jerry Weintraub describes Liberace as a “tortured man” as his new film on the pianist's life heads to the Cannes Film Festival.

Behind the Candelabra, which stars Michael Douglas as Liberace and Matt Damon as his partner Scott Thorson, is set to premiere on Sunday, May 26 on the pay cable network HBO.

The film will also compete for the prestigious Palme d'Or award at the 66th annual Cannes Film Festival, which takes place between May 15-26.

Weintraub, the film's executive producer, told The Hollywood Reporter that he and his wife were friends with Liberace and that he was gay.

“Liberace was a very nice person. But he was a homosexual, and he could not come out of the closet in those days,” Weintraub said. “You just did not do that. Rock Hudson couldn't do it, either. You'd lose your audience. And Liberace's audience was all female. They didn't know he was gay. If he had lived today, the way Elton John and David Furnish live, he could do it. But he couldn't do it then.”

“I went to his home many times for drinks and dinner. He was very nice to me and my wife. He was a wonderful performer. Very flamboyant onstage as well as offstage. He was a happy man. He enjoyed his success, but he also was a tortured man.”
