Crash is a 2004 American crime drama film produced, directed, and co-written by Paul Haggis and Robert Moresco. A self-described "passion piece" for Haggis, the film features racial and social tensions in Los Angeles and was inspired by a real-life incident in which Haggis's Porsche was carjacked in 1991 outside a video store on Wilshire Boulevard. The film features an ensemble cast, including Sandra Bullock, Don Cheadle, Matt Dillon, Jennifer Esposito, William Fichtner, Brendan Fraser, Terrence Howard, Chris "Ludacris" Bridges, Thandiwe Newton, Michael Peña, Larenz Tate and Ryan Phillippe.

Crash premiered at the 2004 Toronto International Film Festival on September 10, 2004, before it was released in theaters on May 6, 2005, by Lions Gate Films. The film received generally positive reviews from critics, who praised the direction and performances (particularly Dillon's) but criticized the portrayal of race relations as simplistic and unsubtle. The film was a success at the box office, earning $98.4 million worldwide against its $6.5 million budget.

The film earned several accolades and nominations. Dillon received nominations for Best Supporting Actor from the Academy Awards, BAFTA, Golden Globe, and Screen Actors Guild. Additionally, the cast won the Screen Actors Guild Award for Outstanding Performance by a Cast in a Motion Picture. The film received six Academy Award nominations and controversially won three for Best Picture, Best Original Screenplay, and Best Film Editing at the 78th Academy Awards. It was also nominated for nine BAFTA Awards and won two, for Best Original Screenplay and Best Supporting Actress for Newton.
