Another good one is the Robert Mitchum classic, "Thunder Road" -- aside from the fact that in the scenes in which Mitchum is supposed to be driving a 1950 Ford, the car sometimes is a '49 and sometimes a '50 (they're easy to tell apart because the '49 had F-O-R-D spelled out across the front of the hood and the '50 had a triangular insignia in that spot instead).
