Proof (1991)

There are two scenes with sex and nudity. In the first, a female attempts to engage in sex with a male and her breasts are exposed. In the second, two characters are engaged in sexual intercourse. The female is scantily clothed and the male is nude, but you barely catch a glimpse of his behind as the camera pans over the two of them on the couch having sex. There is also a scene where the characters are watching a movie and you see a female in the movie have her shirt pulled off exposing her breasts.

The two main characters are involved in a fight scene with a group of hooligans.

In one scene there is some profanity as the two characters tangle with several hooligans. You hear these words used: f*ck, sh*t, poof, faggot, assh*le during the scuffle. Sh*t is used a few times.

One of the characters smokes. There are several times you see the characters drinking wine with a meal.

The characters are watching a "slasher" movie at a drive-in theater where the one character is describing the action (you hear screaming and see a knife) as a killer stalks and kills a female.
