There's one long scene where women dance around topless with decorations on their breasts.

There's one or two other nudity/sex scenes, but they don't last as long as the one described above.

Lots of action but most of it comical (although also crude) fights.

A couple dozen (24 - 36) F-words, and plenty of other language.

A few of the characters smoke cigars/cigarettes.

There's a bar scene where at least one of the main characters is drinking.
