The Sundance Film Festival, the nation's top event for independent film, has mostly been full of dark dramas these last two decades, but this year, organizers promise a broader range of movies.

The festival, which starts today, will be celebrating its 25th anniversary founded as a place to showcase new or experimental voices. The Robert Redford-founded festival is now stepping away from movies that are grim and despairing.

The films that are most talked-about include Brooklyn's Finest, a star-studded cop drama, Mary & Max, a high-profile animated opening-night film, director Marc Webb's romance 500 Days of Summer, and I Love You Phillip Morris, which Jim Carrey plays a con man falling for a male prison inmate.
