Y tu mamá también is a 2001 Mexican coming-of-age sex comedy road film directed by Alfonso Cuarón, who co-wrote the script with his brother Carlos. It follows two teenage boys who take a road trip with a woman in her late twenties and stars Diego Luna, Gael García Bernal, and Maribel Verdú, with narration by Daniel Giménez Cacho. It is set in 1999 against the backdrop of Mexico's political and economic realities, specifically at the end of the uninterrupted seven decades of presidents from the Institutional Revolutionary Party and the rise of the opposition led by Vicente Fox.
