The story was adapted for the screen by Alan Trustman and Harry Kleiner, based on the novel titled Mute Witness (1963) by Robert L. Fish (aka Robert L. Pike). Lalo Schifrin wrote the original music score, a memorable mix of jazz, brass and percussion.

The movie won the Academy Award for Best Film Editing (Frank P. Keller) and was nominated for Best Sound. Writers Trustman and Kleiner won a 1969 Edgar Award from the Mystery Writers of America for Best Motion Picture Screenplay.

Bullitt is most-remembered for its central car chase scene through the streets of downtown San Francisco, one of the earliest and most influential car chase sequences in movie history. The scene had Bullitt in a dark "Highland Green" 1968 Ford Mustang G.T.390 Fastback, chasing two hit-men in a "Tuxedo Black" 1968 Dodge Charger R/T 440 Magnum.

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".

Frank Bullitt is selected by Chalmers, a politician with ambition, to guard a Mafia informant. Bullitt's friend is shot and the witness is left at death's door by two hit men who seem to know exactly where the the witness was hiding. Bullitt begins a search for both the killer and the leak, but he must keep the witness alive long enough to make sure the killers return. Chalmers has no interest in the injured policeman or the killers, only in the hearings that will catapult him into the public eye and wants to shut down Bullitt's investigation.

To protect Ross, Chalmers asks the SFPD to assign Detective Lieutenant Frank Bullitt and his partners, Sergeants Don Delgetti and Carl Stanton, to guard him at a flophouse near an overhead freeway.
