Snowcapped mountains and a winter frost set the stage for the 2010 Sundance Film Festival. The stars bundled up to promote the latest projects they have tucked up the sleeves of their winter coats.

The snow delayed the arrival of Ben Affleck for the premiere of 'The Company Men.' But, ET waited around to talk to him about the festival and the film. Attending the annual event since 1996 when he was supporting 'Chasing Amy,' the veteran Sundancer said, "I've been lucky to be able to be a part of this festival as it's grown."

His snow angel Jennifer Garner and little snow bunnies, Violet and Seraphina, stayed at home in the warmer Los Angeles weather where the white stuff can only been seen in the far distance.

Ryan Reynolds had to face his claustrophobia for his role in 'Buried Red.' Putting on a brave face, the actor admitted, "That is a personal fear of mine; a very deep seeded fear from when I was very young."

'Sympathy for Delicious' star Orlando Bloom took on the role of The Stain because of his respect for the film's director Mark Ruffalo. He said, "I read it. I loved it. I thought to be directed by an actor would be a first and would be interesting. And I've always been a huge fan of Mark as an actor and just as a guy. It was everything I hoped it would be." He described his character as "a completely mad, belligerent rock n' roll northern[er]."
