Near the end of the 1982 TV movie Michael Knight has been shot in the shoulder but as he is driving KITT there is a slip up. Apart from the fact he is steering KITT with the arm that has the shot shoulder - ouch?) the shoulder he has been shot in swaps sides 2 or 3 times! I believe it's just the negative being reversed during editing but its a bit of a major slip.
[1:01.2 - Pilot Episode - After Michael gets shot, he races to his car grasping his left shoulder to contact Devon. Upon contacting Devon, he is grasping his right side. When he finished with Devon, he returns grasping the left side again.]
