Secrets Of TV’s The Rifleman: More Than Just Guns And Good Times

Trekkie Tie-In

Paul Fix appeared in the (second) pilot episode of Star Trek, “Where No Man Has Gone Before,” as Dr. Mark Piper. When the cult sci-fi show was picked up by the network, Fix was replaced by DeForest Kelley. However, “Where No Man Has Gone Before” was eventually the third episode aired in season 1, meaning Dr. McCoy appeared as the ship’s physician before Dr. Piper.
