A movie based on car designer Carroll Shelby and driver Ken Miles. American car designer Carroll Shelby and driver Ken Miles fight with corporate interference and try to figure out the laws of physics to build a revolutionary race car for Ford and challenge Ferrari at the 24 Hours of Le Mans in 1966. This is a very good movie based on a true story. It is unfortunate what happened during a test drive which turned into a tragedy. This is very interesting to see how things changed for NASCAR.
