Found this one yesterday. All in all, 33 minutes of very nice footage of the 1968 race. As a bonus, it has an English voice-over narration (the original film is in French). And best of all, this time there isn’t that typical gut-wrenching seizure-inducing awfully terrible elevator music that you hear a lot in many of the 60s and 70s documentaries.
PS: This is the third nice film I found about the 1968 race. While from some years you can’t find zilch, for some reason 1968 was prolific.
