I must admit to watching this with emotions moving from the first 30 minutes when I was wishing that today's Le Mans had the atmosphere of those days to the numb horror of watching the accident over and over again during the second half of the film.
It's difficult to imagine what the suffering must have been like if you (a) were directly involved or (b) witnessed the event at close quarters.
Afterwards I didn't move from my seat for a while in shock.
I know we moan about the catch fencing these days but that tragic accident occured almost exactly where I watch the first couple of hours of the race. There is a small memorial on the track wall. Any additional physical memorial would be too late. It wouldn't hurt any of us though to spend a few moments in reflection during our revelleries just to remember the scenes and those who suffered, including those folks interviewed during the film who clearly still carry those awful memories with them to this day.
