This is a nihilist black comedy about the emptiness of success and riches.
Susan Anspach is an American housewife, 40ish, married to a rich Swede, and living in a palatial Stockholm seaside residence. She's bored and frustrated. Her father-in-law is 80ish and auditioning wives. Her children are helping their grandfather with the auditions. Her husband is always out of town, and when he's in town he won't sleep with her. Gradually, her behavior is becoming more and more erratic.
When she is denied permission to board a plane to Brazil (because she tried to carry oversized gardening shears on board), she falls in with some struggling Yugoslavian immigrants, and is attracted by their zestful, lusty craziness.
This movie is completely nihilistic. All of the characters are painted in very broad comic brushstrokes, ala Dr. Strangelove, and the sets and situations border on the surrealistic. (There's even a dysfunctional clock homage to Dali's "Persistence of Memory")
This is one odd movie, but I liked it a lot. One cannot expect the characters to behave as people really would, but the movie is energetic and hilarious in sections, erotic in other sections, and the production values are impressive.
This was made in 1981. The director never really made a brilliant movie, but he should have. There is so much talent in evidence here.
