Also known as "All About Krystyna."
Structurally, Anna actually does bear some similarity to Joseph L. Mankiewicz's 1950 Best Picture winning masterpiece. The big difference is that Anna is terrible. There is very little in this film that makes sense, dramatically, realistically, or anything, and the bizarre script has some gems that manage to be hilarious, whether intentional or not ("I hate Czech film" is intentional; "You know nothing of culture! All you know is Mickey Mouse and Donald Fuck!" is unintentional). Paulina Porizkova plays Krystyna reasonably well, but very, very little is asked of her, and bizarrely, she gets almost no screen time to develop.
As the titular Anna, Sally Kirkland actually manages to be very good, maybe even borderline great. She milks everything she can out of the script, and that in itself is impressive. Her performance is sad, pathetic, unsettling, and moving. A well-deserved Oscar nominated. But yeesh, what a movie.
