Just got back from the movie. It was entertaining. There was a lot of things that I wish were included but I really prefer documentaries about things like this. For example, the Ford J-car that Miles was killed in did not look at all like a GT40 like in the movie. It would be difficult to show all the contributions of fabrication and design made by Phil Remington in a dramatic movie. The characters were pretty well done and I was surprised at how well I though Damon did at portraying Shelby. The racing scenes were pure Hollywood and were a really negative aspect of the movie to me. I mean, singing while racing; looking over at the driver in the next car; and when you REALLY need to pass somebody, just push on the gas pedal more; etc. I thought the corporate politics and the practitioners thereof were really the bad guys. I don't know the truth of that. I don't remember that in The 24 Hour War or Shelby American but on the other hand, it wouldn't surprise me.
Beyond that, I largely agree with 4129R's assessment.
