Despite having a score composed by John Williams, the film's opening and end title music were lifted excerpts from Touch of Evil (1958) which was scored by Henry Mancini.

Angie Dickinson recalled that Ronald Reagan, an arch-conservative Republican, refrained from discussing politics during filming since President John F. Kennedy had been assassinated and the other members of the cast were Democrats.

According to Don Siegel, it was the policy at Universal at the time to shoot the last scene of the film first. On that first day of filming, according to Siegel and Clu Gulager, Lee Marvin arrived late and had been drinking, but because he had no dialogue, the scenes were used as shot.

When North drives his Cobra into pit row prior to the race that Sylvester recalls, in flashback, a Ford badge is clearly visible on the side. In addition, there are several other Cobras in the race, presumably with Ford badges. Later in the film, Strom states that the heist was four years ago (from 1964), and so the race depicted was even earlier than that. Carroll Shelby did not drop the first Ford V-8 and transmission into an AC Cobra until February of 1962, and Ford did not start selling them until later that year.

Towards end of film, camera shadow is visible on Jack Browning's rifle case as he exits his car.

Early in the movie, Johnnie comes in off the track after a solo test session. There are no other cars on the track and he has "goggle eyes" i.e. dirt on his face except where his driving "glasses" were. Drivers only look like that after having been in a race. Since he was on the track by himself, there would be no source of that dirt (from other cars).

Jack Browning: I approve of larceny; homicide is against my principles.

Charlie Strom: Whoever laid this contract wasn't worried about the million dollars, and the only people that don't worry about a million dollars are the people that have a million dollars.

Charlie Strom: It's not only the money. Maybe we get that and maybe we don't. But I gotta find out what makes a man decide not to run... why, all of a sudden, he'd rather die.
