When it comes to celebrity sightings, few places can beat the Sundance Film Festival in terms of raw numbers. We spotted so many famous faces on Main Street, like William Hurt walking past the nightclub Harry O’s . Danny Glover meanwhile couldn’t take two steps without shaking hands and taking pictures with fans.

Bill Pullman, Michael Keaton, Esai Morales, Armand Assante, singer John Legend and some girl from “High School Musical” (not Tisdale or Hudgens) all made the gift suite rounds at The Dance. And who do we run into at the Greenhouse suite but E!’s tree-lovin' movie critic (and Reel Talk guest host) Ben Lyons.

We also crossed paths with the charming (and sexy) Tilda Swinton on Main Street, directly across from where PETA activists where trying to shame Mary Kate Olsen for apparently wearing fur around town.

Alison interviewed Swinton earlier for the movie “Derek,” which she wrote and stars in. I asked if she was anxious for Tuesday to arrive and she had a blank expression for a second until she remembered it’s the day Oscar Nominations are announced! (trust me, she wasn’t faking. She honestly didn’t remember)

She told us if she’s nominated for “Michael Clayton” (we think she will) she won’t be disappointed if the Writers Strike derails the Oscar event. Why? Because she’s scared to death about doing the whole dog-n-pony red carpet thing! She has no desire to go through the fashion hassle. How refreshing is that?
