Ski Patrol, Police Academy 2, and Airplane the list goes on for 80s movies with a single brief topless shot.
I'd argue the self-aware humor of Airplane was really calling out stereotypes like the one pictured, and defusing tensions with humor. Now Revenge of the Nerds, there's a problematic movie.
Breaking and entering into a sorority, barging into private rooms and house showers/bathrooms, stealing property, and installing hidden cameras in their rooms in order to casually spy on them while they are naked, sleeping, etc. Capturing images of the sorority girls naked, making hundreds of copies of those images, and sharing them with the entire campus to win a school-sponsored competition for a student government seat. Raping a woman while sharing said porn of her and her friends with the entire student body. Said woman then falls in love with her rapist. All played for laughs and zero consequences for any of it. An 80's hit! Make 3 more sequels of it!
Oh shit yeah I forgot about that part. It's been probably 10 or 15 years since I've seen it. I thought the panty raid and hidden cameras were bad, but damn, that movie did not age well.
Airplane was released in 1980, before the PG-13 rating existed. I’m not sure how the film would be rated today, but I’d wager it would not hit PG standards without significant edits.
