Don't mention it...
I've downloaded it yesterday and I share your emotions about this great film. Before this I've only seen some photos from that GP and nothing else.
Funny, but even at first GP the situation was more-less the same as today. Renault, Mercedes and FIAT as top dogs
Another thing, even though Renault was the only car with driveshaft and differential Louis realized that since there are only 4 corners at very long circuit having a functional differential would mean loss of power so he blocked differential!
