At 1.28 that looks pretty real. I am assuming / hoping its a camera on dolly track and someone tugs it on a robe at the last second. I think the footage is speeded up.
2.40 I think thats Hitchcock’s STRANGERS ON A TRAIN
Strangers on a Train (film)
I 3.22 we see the words “dan marruffo ”
I googled “dan marruffo race car movie”
and found :
The Dan Marruffo footage is 2 minutes in…. I suppose thats documentary / newsreel footage of a real race.
I’ll keep searching and keep you posted.
