In the 2006 film Quinceañera, which film festival hosted its world premiere?

The 2006 film Quinceañera had its world premiere at the Sundance Film Festival.

Sundance is an annual independent-film festival held in Utah and organized by the Sundance Institute. The film debuted there before receiving wider theatrical distribution, placing it within the independent-cinema tradition rather than the mainstream studio system.

Quinceañera was written and directed by Richard Glatzer and Wash Westmoreland. Its story follows Magdalena, a teenager in the Mexican American community of Echo Park, Los Angeles, as her planned celebration becomes complicated by family conflict and an unexpected pregnancy.

The film is sometimes confused with a documentary or with a Spanish-language production because its title names a major Latin American tradition. It is an English-language American drama, and its Sundance premiere helped introduce it to festival audiences before its commercial release.
