Bullitt is a 1968 American dramatic crime action thriller film directed by Peter Yates and produced by Philip D'Antoni. It stars Steve McQueen, Robert Vaughn and Jacqueline Bisset. The screenplay by Alan R. Trustman and Harry Kleiner was based on the 1963 novel Mute Witness by Robert L. Fish, writing under the pseudonym Robert L. Pike. Lalo Schifrin wrote the original jazz-inspired score, arranged for brass and percussion. Robert Duvall has a small part as a cab driver who provides information to McQueen. In 2007, Bullitt was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". Ambitious politician Walter Chalmers (Robert Vaughn) is about to present a surprise star witness in a Senate Subcommittee hearing on organized crime. The witness, Johnny Ross (Pat Renella), a defector from the Organization in Chicago, is put under San Francisco Police Department protective custody for the weekend, 40 hours until his Monday morning appearance. To improve his own image, Chalmers requests SFPD Lieutenant Frank Bullitt (Steve McQueen), well-liked by the local media, to take charge. Bullitt and his team, Sergeant Delgetti (Don Gordon) and Detective Carl Stanton (Carl Reindel), put Ross under around-the-clock protection in a cheap hotel selected by Chalmers. Late Saturday night, while Bullitt is with his girlfriend (Jacqueline Bisset) at a restaurant, Stanton is on solo duty when the desk clerk unexpectedly calls to announce that Chalmers wants to come up. While Stanton checks by phone with Bullitt, Ross inexplicably (at the time) unchains the hotel room door. A pair of hitmen (Paul Genge and Bill Hickman) burst in and shoot Stanton and Ross, seriously wounding both.
