I agree with the Jean-Paul’s overall rating. As an actual car enthusiast I’d like to out a few things in the movie that are actual history without giving away the whole story.

1. The feud between Ford and Ferrari was real and unfolded essentially as portrayed.
2. 80s kids will know Lee Iacocca as a Chrysler executive but he did come from FoMoCo. He did push the company to compete in the performance market. The Mustang was essentially his baby.
3. I don’t know the reality of Shelby’s relationship with the various people in the movie was, but he was notoriously stubborn and confrontational.
4. As far as I can tell the main FoMoCo antagonist, Leo Beebe, is a creation of the movie.
5. The storyline of Ken Miles role in developing and driving the car are accurate. This includes the race outcome and his test driving throughout the movie.
6. The cars depicted in the race scenes looked period correct to me.

In short, a pretty good portrayal of the facts.
