The two best racing movies? Frankenheimer's GRAND PRIX and the Steve McQueen passion project, LEMANS.
Both filmed in their day, with the drivers of the time (you'll see Phil Hill several times in GP, and even J-M Fangio) and their cars (fill in the blank that James Garner is driving a doppelganger for Honda), and the footage of the Great White Shark of endurance racing, the Porsche 917 in all its rage, and the Ferraris and other cars, both these movies are historically correct time capsules of a world of European racing that long gone, but not forgotten.
