Who co-wrote the screenplay for the 2006 film Quinceañera with Wash Westmoreland?

Richard Glatzer co-wrote the screenplay for the 2006 film Quinceañera with Wash Westmoreland.

Glatzer and Westmoreland worked together as the film’s writing and directing team. Their screenplay follows Magdalena, a teenager in Echo Park whose approaching quinceañera becomes entangled with pregnancy, family pressure, religion, and community expectations.

The film’s cultural setting is specific, but its dramatic concerns are broader. The quinceañera functions as a public family milestone, meaning that private conflicts become difficult to hide. That tension gives the celebration a structural role in the screenplay rather than treating it as decoration.

Glatzer and Westmoreland later collaborated on Still Alice, released in 2014 and directed by both filmmakers. That later film is unrelated to quinceañera customs, but it is part of the pair’s continuing creative partnership. The requested answer is Glatzer, who co-wrote and co-directed Quinceañera.
