Bernal hits Sundance to share tragic border story

(AP) Gael Garcia Bernal has journeyed north to the Sundance Film Festival in Utah to share the tragic story of another traveler.

The Mexican actor is a producer on the immigration documentary Who Is Dayani Cristal? in which Bernal also appears on-screen to dramatize the path that the film's subject took to the U.S.

Bernal and director Marc Silver sought to unravel the mystery of a body found rotting in the Arizona desert in August 2010. The man bore the tattoo Dayani Cristal across its chest.

The film reveals the circumstances that led the man on a 2,000-mile trek that ended in the desert. And it provides a tearful answer for its title when it reveals the identity of Dayani Cristal.

The film premiered as part of Sundance's day-one lineup Thursday.
