I knew nothing about this movie except for Ron Howard is the director and it had kind of a lame title, well I just finished it and was blown away. I think it just became one of my favorite sports movies ever and Daniel Bruhl was amazing as Niki Lauda. This movie didn't get nearly enough marketing and or was marketed poorly.
It was marketed pretty well. Problem is that that the story is pretty unfamiliar even if it was about probably one of the best seasons ever in any sport. From what I understand, Ron Howard wasn't even an F1 fan when he opted to make it. As far as racing movies go, it's in second place behind Le Mans, and ahead of Grand Prix (which is still pretty damn good).
The script is pretty damn good and covers a great deal of ground, not just the rivalry between Hunt and Lauda, but the politics and danger of F1 at the time as well as the ride buying.
Ricky Bobby doesn't count, and Driven and Days of Thunder are too stupid to remember.
