I was watching Wagon Train on You Tube. Fans of John Wayne movies will recognize Ward Bond. I watched a hysterical episode where Wally Cox turns everything upside down. Indians hold children and Wally Cox wants to solve things peaceably. He does in a hysterical bit of comedy using science and music.
Wagon Train also has what is likely the last appearance of beloved comedian Lou Costello in an nontraditional role. Here he plays the charming drunken father figure to a runaway girl. You also see clearly that if cast in the right role he could act.
