Hollywood's brightest stars and indie film's freshest faces hit Park City, Utah for the Sundance Film Festival, and in between the screenings and parties, some of our favorite actors—like Naomi Watts and January Jones—warmed up at InStyle's photo studio, hosted by the Grey Goose Blue Door. Kate Bosworth swung through with the cast of Big Sur, a film directed by her partner, Michael Polish. "This year, I’m with the love of my life," she told InStyle of her festival experience. "It’s wonderful to wake up in the morning with not only your artistic partner but your lover and tackle the day. I’m so proud of the film and I’m so proud of him and I’m so proud of what we did together that it’s a wonderful experience to be here." Click through the gallery to see six never-before-seen photos from inside the studio, and then flip to page 133 of InStyle's brand-new April issue—or download it to your iPad, Nook, or Droid tablet—to see even more beautiful snaps by celebrity photographer Eric Ray Davidson.
