Goofs

During the Brands Hatch race, Hill and Yamura are watching the action on track from the pit lane. They face the part of the circuit behind the pit lane. Aron's car has developed a fault and Hill shouts, noticing that Aron's car is leaking fuel. The cars continue around the circuit and come onto the pit straight. Aron's car is now on fire. Hill now proclaims "It's on fire!" but he is still in the viewpoint that he was before, meaning that he would've been looking in completely the wrong direction and would not have seen the flaming car from that precise point.

After Jean Pierre crashes he is helped out of his car. He pulls his goggles part way down as they are now just under his lip and covering his chin. The view then cuts to a close-up of Jean Pierre's face and the goggles are not over his face any more.

Prior to the start of the race at Monza, there is a flag ceremony at the starting line. The US flag has 48 stars instead of the 50 it should have had in 1966.

A banner in the town square heralds the 37th Annual Gran Premio d'Italia. 1966 marked the 57th edition of Monza.

When Stoddard's car crashes in the first race, you can see a white tendril of smoke shooting out towards the car. This is the hydrogen pump used to propel the fake formula 1 car with a dummy in it to make the crash seem more realistic and should not be in the shot.

The Academy Award Winner for Editing could not save a painfully long scene where an extra violated the golden rule actors must NEVER do.

Frankenheimer set up Panoramic view of the table

Like a movie viewer ON CAMERA, an extra stared at Sarti & Louise enter, Nino & Lisa leave, then imbalance the camera frame as he dropped his glasses staring into the camera lens. All the attention was on him.

Why Frankenheimer used the shot may have cost him the Oscar. Extras as well as actors must NEVER Stare into the camera lens, but he did.

A still-crippled Stoddard begins to drive again yet cannot bend his left leg as he climbs into his brother's old car. If he can't bend his leg, he would be unable to operate the clutch.

At around 55m The Waiter at the end of the buffet keeps looking at the camera or the actors as though wondering if a take was happening.

During the Circuit National De Francorchamps, the course is dry and manageable. All of a sudden Sarti's car is in a down pour, on a dangerously slick racing environment.

This is not the work if an Academy Award Best Editing winner.

No, it did win BEST Editing.

Grand Prix WON Best Editing at the 1966 Academy Awards.

Spa, which was nearly 9 miles long, was notorious for having weather conditions change dramatically from one side of the circuit to the other.

During the presentation of flags prior to the Italian Grand Prix, the U.S. flag being displayed is the old 48-star version, which would have been a decade out-of-date at the time of the movie.

At 20:26: After the crash involving Aron and Stoddard, a group of reporters follow Stoddard on a stretcher. One person is filming using a 70mm Super Panavision camera alongside a sound man with a microphone. They were part of the production crew, as this was the format in which the film was shot.

The camera's shadow can be briefly seen on the racetrack as Scott and Pete duel wheel to wheel, passing and re-passing each other using drafting.

Near the end of the Monza GP, Sarti is passing Dan Gurney in the Eagle. You can see the huge cinema photography camera strapped to the front end of the Eagles car.
