Leaving the warmth and sunshine of L.A. to promote her new movie, Zoe Saldana attended the premiere of "Infinitely Polar Bear" at the 2014 Sundance Film Festival on Saturday (January 18).

The "Avatar" star smiled brightly in a black sweater over her white button-down shirt with black skinnies and boots.

In the movie, a manic-depressive father tries to win back his wife by attempting to take full responsibility of their two young, spirited daughters, who don't make the overwhelming task any easier.

Written and directed by Maya Forbes, Zoe is joined by Mark Ruffalo, Keir Dullea, Wallace Wolodarsky, and Mary O'Rourke in the cast.
