Everyone has their reason for coming to Sundance: movies, networking, making money, making off with swag, making out, usually while drunk. But there's also the skiing and snowboarding. It's a rare pleasure to see the celebrity taking time off from promoting his or her movies to hit the slopes, but most do at least once: Woody Harrelson, for instance, has gone snowboarding nearly every day since he's been here. Paris Hilton got in a day of skiing (though she may be a liar about how good she is). And on Monday, Eliza Dushku, Matthew Rhys, and Dave Annable (from Brothers & Sisters) all made valiant attempts to tame the fluffy white beast.
