Who directed the 2006 American film Quinceañera, which won the Sundance Grand Jury Prize?

Wash Westmoreland and Richard Glatzer directed the 2006 American film Quinceañera.

The film follows Magdalena, a teenager in Los Angeles whose expected quinceañera becomes complicated by pregnancy and family conflict. Its story uses the celebration as a setting for questions about identity, family expectations, religion, and belonging in a Mexican American community.

Quinceañera premiered at the 2006 Sundance Film Festival, where it won both the U.S. Dramatic Grand Jury Prize and the Audience Award. The recognition helped bring the independent film to wider attention and made its title familiar beyond the celebration itself.

Westmoreland and Glatzer were filmmaking partners and later collaborated on Still Alice, which earned Julianne Moore the Academy Award for Best Actress. The film title is sometimes confused with the 1987 Mexican television series of the same name, but the two are separate works.
