Men ogle beautiful women, and women ogle beautiful men.

A very aggressive woman pursues a man throughout the movie, despite his clear lack of consent.

Some of the costumes are risqué for the 1940s, but fairly tame now. For example, short skirts on dancers who get flipped so the audience sees their hot pants underneath, or skirts being pulled off to show pantaloon-style undergarments.

Some gunfire, but no one is injured.

As a slapstick film, there's plenty of comedic violence in the form of hitting and fighting.

Since the name of the film, and the play-within-the-play, is "Hellzapoppin," hell is said several times.

As a film from the 1940s, there's regular smoking and drinking of the characters.

The film starts briefly in Hell, but as a black-and-white film played for laughs, it is unlikely to be very frightening to anyone, even small children.
