Snow, Schmoe. For all the A-listers (and B-listers, filmmakers, promoters, producers, reporters, photographers, tag-alongs and wannabes), all that white stuff didn't really matter too much on opening weekend at the Sundance Film Festival.

Stars (think Aziz Ansari, Robert Redford, Joshua Jackson, Neil Young and Bruce Willis) flooded into the Bing Bar to attend cocktail parties for films "Excision" and "Neil Young Journeys" and to sit on a panel with the cast of “Lay the Favorite.” (One of the film's stars, Catherine Zeta Jones, had to skip out despite inital plans to attend.)

Others, like Utah-transplant and co-owner of SLC's Bar X, Ty Burrell, stopped into the Sorel lounge on Main Street with “Modern Family” co-star Nolan Gould to test out a pair of the brand's heavy duty boots, which were probably put to good use as he schlepped up and down Main Street.

Anthony Mackie, who co-starred in the Oscar winning “The Hurt Locker,” tried on winter-friendly kicks at both the Sorel and Timberland lounges with his snowboard instructor in tow and plans to hit the slopes Sunday. “I learned to ski watching TV, so I've got this,” Mackie, a New Orleans native, told Salt Lake magazine. “Half a day on the kiddie slopes and I'll be fine.”

Edward J. Olmos, Allison Janney, Kristen, Chris Kattan, Jason Ritter, Michael Cera, Spike Lee, “Bachelor” Ben Flajnik, William H. Macy and Danny Glover were all spotted trekking through the day-long onslaught of snow, many popping into the swag suites hosted by big brands at local shops like Flight Boutique and Mary Jane's.

The Utah Film Commissions set up shop next door—the first time the agency has had a Main Street presence during the fest—to the ASCAP Music Cafe, where Natasha Bedingfield and Josh Kelley (aka Mr. Katherine Heigl) played to packed crowds.

“It makes it very easy for people to come in and for us to educate them on the state of film in Utah,” said film commission director Marshall Moore of the film panels and hospitality suite.
