At which 2006 film festival did Quinceañera win both the Grand Jury Prize and Audience Award?

Quinceañera won both the Grand Jury Prize and the Audience Award at the 2006 Sundance Film Festival.

The film premiered at Sundance, the major American festival known for highlighting independent cinema. Its two dramatic-competition awards gave the movie significant early recognition and helped establish it as a notable independent film about Mexican American family and community life.

The awards belong to the film Quinceañera, not to a real-life quinceañera ceremony. The movie was directed by Wash Westmoreland and Richard Glatzer and stars Emily Rios as Magdalena. Its story is set in Los Angeles and uses an approaching fifteenth-birthday celebration as a framework for exploring family conflict and social expectations.

Sundance is held in Utah and is separate from festivals such as Cannes, Toronto, and Venice. Those festivals are also internationally prominent, but they were not the venue for these two 2006 awards.
