Many viewers thought that because "Old Charlie" the town drunk would usually be thrown through the saloon doors (or window), bounce off a support post, fall face forward over the hitching rail, spin around and land on his face or back that he was actually a young stuntman in "old man" make-up. In reality, "Charlie" was ace stuntman Harvey Parry, who at that time was 65 years old and had been a stuntman for almost 45 years.
