Bullitt (1968)

Continuity mistake: Steve McQueen passes the same green Volkswagen at least three times while chasing the black Dodge Charger R/T. This is due to the same downhill portion being shown to us from multiple angles to artificially extend the length of the scene.

Trivia: In the restaurant scene near the beginning of the film, the actor playing the waiter accidentally flips the corner of the menu in Steve McQueen's eye, but it was left in the finished film.

Question: Just after (the real) Ross has been shot at the airport, you hear the babble of bystanders' voices. At one point you apparently hear this exchange: Person 1: "I heard he shot someone" Person 2: "He's a c**t, that's what he is". Is this part of the script, a mischievous foul-mouthed extra or my bad hearing?
