Joan Rivers documentary reveals her passion

LOS ANGELES "I would love to do another late night talk show. I would love to go back to Broadway with my show," said comedian Joan Rivers. "Melissa and I are starting a new reality show called 'Mother Knows Best.' I've never done a movie. I've never been in a real situation comedy."

Joan Rivers lives to work. It's as simple and as complicated as that, as we discover in the documentary, "Joan Rivers: A Piece of Work." The film examines Rivers' drive to stay in the game. While honestly showing the highs and the lows that go with it.

"I love the work. I am very driven," said Rivers. "I literally lie in bed sometimes and say, 'So what did I do today that will help the career?' Even on a Sunday."

Joan also acknowledges some of the work she used to get now gets to her friend, Kathy Griffin.

"I adore Kathy. She's the new piece of candy in the box," said Rivers. "Of course she's getting it. And I get it. I'm not thrilled about it so when we have dinner I let her pick up the check now."

One look at her New York home, though, and you think "Joan of Park Avenue." She works hard for her money and she's also generous with it. But the joy of giving is trumped by the sheer joy she gets in performing.

"I once was talking to Frank Sinatra and he pointed to a stage in Las Vegas and he said, 'That's my house.' And I understood," said Rivers.

"Joan Rivers: A Piece of Work" opened in limited release Friday. Some tickets are still available for Q&A sessions with Joan after screenings Saturday night at the Landmark Theatre in West Los Angeles.
