Curly Howard had suffered a series of strokes in 1945 that forced him to leave the team. His cameo (as the man asleep on the train - with long hair and a clothespin on his nose) was intended by brother Moe Howard as a morale booster, but Curly never made another movie.
In one scene, The Three Stooges are sitting in front of a lion. If looked at closely, it can be noticed that there is a glare behind them. There was a sheet of glass put up between them and the lion for the scene's shooting. Even though the lion was old, docile, and tame, Shemp Howard panicked and refused to do the scene. As a result, the glass was put up to separate them from the lion.
The first appearance of the updated, faster version of "Three Blind Mice", arranged by 'Lyle Spud Murphy'. With minor updates, it was used until their final shorts in 1959.
Though Curly's screen time in this film lasts roughly twenty seconds, it marks the only time he ever appeared on screen with his brother Shemp, the only time all three Howard brothers ever appeared together and the only time four stooges appeared together.
Debut of Emil Sitka in a Stooges short featuring Shemp. In an interview around 1990, Sitka described the three as absolute professionals, although during rehearsals or between filming scenes they would often get into violent arguments using the "saltiest" language.
