While there is no real sexual activity shown in the movie, it is littered with sexual inudenos that are used to contribute to the comedic bits thruoughout the show. The most you see visually is the scene where Lisa shows her father her nightie (which is only considered a nightie by the 1930's standards...to several celebrities it'd be considered a cute outfit) to show him that she has reached womanhood. There is no sexuality intended in the gesture.
The only scene that shows any violence is when "Snapps" pins Anthony on the breakfast table. There is, however, several scenes that contain threats to "Pop" characters in this show. Again this is all used only to contribute to the comedic bits thruoughout the movie.
There are few (and I mean once or twice) references to drugs. There is a scene where Marissa Tomei is smoking a cigarrette. Also the whole story is based in the time of prohibition and the main character "Snapps" is an "Ex-Gangster" that sells beer. They never show any drinking of alcohol but there is mention of it.
