Main Street Mischa

The star sightings continue at this year's Sundance Film Festival in Park City, Utah. Mischa Barton left the warm weather of the O.C. to attend the fest, and was seen wisely walking around town. I don't think we'll see her driving  anytime soon! Other stars sighted under layers of warm duds included Maria Bello, Anjelica Huston, Adrian Grenier, Lauren Graham and in the "what are they doing here?" category, MTV reality vixen Audrina Patridge.
