How much racing?
I've never seen this movie before, but now that I know it's set in the world of F1 during the mid-70's, I am interested to know how much racing footage there is.
I did see a clip on youtube about a fiery crash, and I remember seeing an article about how it was done many years ago in National Geographic's "World" (their magazine for young readers). I had no idea what movie it was from, but I distinctly remember the red Martini car (the Brabham).
