In his final interview with Oprah Winfrey, pianist Liberace said people don't know who he really is.

Liberace is the subject of the film Behind the Candelabra, which premiered in the United States on pay cable network HBO on Sunday.

The film, which stars Michael Douglas as Liberace and Matt Damon as his lover Scott Thorson, premiered earlier this month at the Cannes Film Festival in France, where it competed for the prestigious Palme d'Or award. The lesbian love story Blue is the Warmest Colour: The Life of Adele won the festival's top prize.

Liberace, who died on February 4, 1987 of AIDS complications, never publicly acknowledged that he was gay.

In late 1986, Liberace gave his final interview, appearing on the Oprah Winfrey Show.

“What is it you really want people to know about you?” host Oprah Winfrey asked.

“People know I do all those things you mentioned,” Liberace answered as he reclined on a piano. “But they don't know me as a private person. They don't know what makes me tick when I'm not on stage. And I love being a human being. You know.” (The video is embedded on this page. Visit our video library for more interviews.)
