Hmm, Rendezvous....
A great film and soundtrack, but an optical illusion nonetheless (then again, which films aren't?). I think someone worked out the average speed at about 40mph or maybe even less, and when it sounds like he's maxing it in 4th gear (which should be well over the ton) he's actually doing about 60. I think it was Spirit Level Films that did a great re-mastering job a couple of years ago.
I think it's got to be Bullitt, but there's a good choice out there. Both the Bourne films had a great chase, a mini in the first, and I forget what in the second. I forget so much...
