Stars Show for Premiere of Gore's Global Warming Documentary

Hollywood rolled out the green carpet Tuesday for former Vice President Al Gore and his global-warming documentary, "An Inconvenient Truth."

Actors and activists attended the opening of the film, which argues that global warming is imminent and potentially catastrophic.

Sharon Stone, David Duchovny and "Curb Your Enthusiasm" star Larry David, as well as comedian Garry Shandling, were among the star-studded crowd, where guests walked a green carpet instead of the traditional red.

"It's just the environment and planet, that's all," Shandling said.

One event sponsor, Hewlett-Packard, brought guests from a hotel in a vehicle powered by biofuel instead of gasoline.

Others attending included snowboarder and Olympic gold medalist Shaun White, who said he was interested in global warming because he believed it had reduced snow pack.

"The lower elevation mountains are not getting as much snow," said White, known as the "Flying Tomato" because of his red hair.

White said the sport would suffer if "you can't go to your local mountain and ride."
