Kill Bill: Volume 1 is a 2003 American martial arts action film written and directed by Quentin Tarantino. It stars Uma Thurman as the Bride, who swears revenge on a group of assassins (Lucy Liu, Michael Madsen, Daryl Hannah, and Vivica A. Fox) and their leader, Bill (David Carradine), after they try to kill her and her unborn child. Her journey takes her to Tokyo, where she battles the yakuza.

Kill Bill was inspired by 1970s exploitation films and martial arts films. It features an anime sequence by Production I.G. Volume 1 is the first of two Kill Bill films made in a single production. They were originally set for a single release, but the film, with a runtime of over four hours, was divided in two. This meant Tarantino did not have to cut scenes. Volume 2 was released six months later.

Kill Bill was theatrically released in the United States on October 10, 2003. It received positive reviews and grossed over $180 million worldwide on a $30 million budget, achieving the highest-grossing opening weekend of a Tarantino film to that point.
