Hitman's Run - The Kid Shrunk
Eric Roberts is in a car chase with 'the kid' as he calls him. The kid happens to be about 2 inches taller than Eric when they're walking side by side yet when they're in the car chase and you see outside shots of the pair in the car, the kid appears to have shrunk about 3 feet when sitting next to Eric. This happens quite a few times in the movie.
