Gripping documentary that follows Steve McQueen in his quest to make 'the ultimate racing movie', 1971's Le Mans.
There is a Matra featured at the beginning so I am allowed to post it.

I watched it last night and found it very enlightening and also disturbing. A strange philandering man indeed.......
Highly recommend you watch it!
