Not surprisingly, it was a star-studded weekend at the 2013 Sundance Film Festival, with boldfaced names including Matthew McConaughey, James Franco, Rooney Mara, Joseph Gordon-Levitt, Naomi Watts and Jessica Biel among those turning out to support their latest projects. Hell, even rock royals Dave Grohl, Steve Nicks and Ringo Starr hit Park City for the annual indie-film blowout, the former two to promote the Foo Fighter frontman's directorial debut "Sound City."

Care to see who else bundled up to hit the red carpet over the weekend? Check out the gallery below for all the star-studded pics.

The Sundance Film Festival runs until January 27.
