Inglourious Basterds is a 2009 epic ensemble war film written and directed by Quentin Tarantino. It is set in Nazi-occupied France during World War II and has the largest number of speaking roles of any Tarantino film to date and was filmed in several locations, among them Germany and France. Filming began in October 2008. The title (and partial premise) of the upcoming film are inspired by Italian director Enzo Castellari's 1978 movie Inglorious Bastards, but it is not a remake of that film.

The director has repeatedly stressed that despite it being a war film, the movie will be his "spaghetti-western but with World War II iconography". In addition to spaghetti-westerns, the film also pays homage to the World War II "macaroni-combat" sub-genre (itself heavily influenced by spaghetti-westerns), as well as films by Jean-Luc Godard.

The film was accepted into the main selection at the 62nd Cannes Film Festival in competition for the prestigious Palme d'Or and had its world premiere there in May. It wound up being the only U.S. film to win any award in Cannes, earning a Best Actor award. The Weinstein Company has stated August 20, 2009, as the tentative U.S. release date.
