Facets Multimedia Sexmission [dvd] [polish W/english Sub] 5.1 Dol Dig
One of the best Machulski comedies!
This is a very watchable film for westerners.  Most of the comedy is timeless (poking fun at women's lib and the gender wars) but there's also a lot to observe in the background such as Polish culture and 1970/80's sci-fi effects and fashion.  Much of the filming was done at the famous Wieliczka salt mine.  There's a big deal made about the nudity but it's mostly casual and there's no sex either.  Imagine Benny Hill meeting Dark Star.
