@Ruggercat68, my favorites were the stunt doubles used during fight scenes on the original Star Trek series. William Shatner and the other actor would lunge menacingly at each other and then the scene would cut to stunt doubles who looked nothing like the actors. They would do everything they could to hide their faces while "fighting". When one stuntman threw the other one against a wall, the scene would cut back to William Shatner wincing as he slid down that wall to the floor. The camera trickery may have been able to fool us kids at the time, but now it looks really obvious.
