21 Grams is a 2003 film written by Guillermo Arriaga and directed by Alejandro González Iñárritu. It stars Sean Penn, Naomi Watts, Benicio Del Toro, Charlotte Gainsbourg, Melissa Leo and Clea DuVall.

Like Arriaga and González Iñárritu's previous movie, Amores perros, 21 Grams is a movie which weaves several plotlines around an automobile accident. Penn plays an ill mathematician, Watts is a grieving mother, and Del Toro is an ex-convict who has newly discovered his Christian faith and his family. Their lives come together at the accident scene.

The movie was nominated for Academy Awards for Best Performance by an Actor in a Supporting Role (Benicio Del Toro) and Best Performance by an Actress in a Leading Role (Naomi Watts).
