This is in German but, according to imdb, is in fact an Austrian movie. The imdb says it was released in 1973 but the rip I found is tagged 1972. Take your pick.
Since I don’t speak the language, I don’t exactly know what it is about (if anything), but it has the same staples as 70s German sex-comedies : lots of nudity and fornicating people plus less-than-hilarious (therefore irrestistible) gags, such as a man sneezing while he kisses a woman. Also, and I swear I’m not making this up, this one has talking cars. See if it doesn’t !
Actors: Anne Graf / Erich Padalewski / Monica Marc / Reinhard Reiner
