Boring characters, boring script, boring story, full of inaccuracies and over-the-top dramatizations. Very little that is shown on screen happened in real life.

We see way too little of Henry Ford II and Enzo Ferrari. Basically, they each had a scene and that's it. Leo Beebe took way too much screentime. Also, too many pointless scenes with Miles' son or with Shelby and Miles arguing bloated up the runtime of the movie.

[spoiler]In reality, Henry Ford II didn't need to be persuaded to enter motorsports. He always wanted to have a Ford run the Le Mans. We never see how the first car was designed and built in England. It's not even mentioned that the first three versions were based on a Lola Mk6, probably the most innovative car of its time. Only the MkIV that won the 1967 Le Mans was designed and built in America.[/spoiler]

[spoiler]Caroll Shelby wasn't part of the team from the beginning, he was brought in after the disappointing debut season of 1964.
The Ferrari 330 P3 was not as competitive as the Ford GT40 MkII. By nightfall, Bandini's Ferrari was at 12th place and the GT40 MkII's held comfortably the 1-2-3-4 positions.[/spoiler]

[spoiler]During the final hours of the race, Miles & Hulme's car had a 4-lap lead on their teammates McLaren & Amon, but the #1 car had to pit one more time to switch out a wrong set of brake rotors which cost them most of their lead. Now, Miles gets the team order to back off so that he can finish neck-to-neck with McLaren (the 3rd car was 12 laps behind). Miles lets McLaren catch up but decides to slow down further right before the finish line in protest, thus allowing McLaren to win by more than a car's length.[/spoiler]

[spoiler]In the end, it was a battle of attrition. Only 3 of the 13 Fords finished and only the two 275 GTΒs (and none of the 330 P3s) finished from the 14 Ferraris entered, while Porsche managed to finish all four 906 cars in positions 4-5-6-7.[/spoiler]

And something that really bugged me: [spoiler]Miles' brakes overheated IN THE RAIN!! Fucking ridiculous. Not only is traction on the wet limited, so Miles wouldn't be able to brake as hard because his tires would be slipping, but the rain would also have cooled the brakes and not allow them to overheat to the point of glowing red-hot. I guess the director wanted the recurring theme of failing brakes for the last accident, which is not how it happened in real life. Miles' prototype J-car had some untested aerodynamics which caused his crash at the end of the long back-straight, and the aluminum honeycomb chassis proved too weak and shattered, bursting the car into flames, killing Miles.[/spoiler]

You'd be better off watching Steve McQueen's Le Mans from 1971.
