Blooper in Town Without Pity
Watch the very end as Kirk Douglas is walking down the hotel corridor towards the open door. Thru the door you will plainly see the rear quarter panel of a 1957 Chevy Convertible with wide white wall tires. Soon as the camera switches to an outdoor shot, you will see Kirk getting into that car which has changed into a 1956 Chevy Convertible with blackwall tires.
Great movie.
