"Anna" is the movie with perhaps the greatest disparity between my opinion and everyone else's, so seems appropriate for my first comment on IMDb.
Anna (Sally Kirkland) was a legendary actress in Czechoslovakia, and in New York suffers a career in shabby productions with avant garde or artistic pretensions. Krystyna (Paulina Porizkova), an immigrant from Czechoslovakia with acting aspirations, spends her first days on the streets of New York searching for Anna, fainting from hunger virtually on her doorstep. Anna takes her in, and they become intimate friends.
Porizkova's Krystyna is as compellingly ambitious and wily as any of Werner Herzog's roles -- and this in an area calling for a subtler social sense. Krystyna seems not to be Anna's daughter, given up for adoption at a young age. But the malleability of memory -- Krystyna's in an obvious way, though perhaps also Anna's -- is treated more interestingly than in some of Agnieszka Holland's better known movies, such as "Olivier, Olivier" or "Europa, Europa." Almost as interesting as some real life cases: The erstwhile mental illness "fugue" comes to mind (see, for example, the Times Literary Supplement, 16 July 1999; as this is a movie database, I'll also point to "Paris, Texas" for a portrayal of the phenomenon). So does the case of Benjamin Wilkomirski. I could but won't extend this list.
On the negative side, the description of Jewish life in New York is a mixture of inappropriately projected Christian norms and condescension (maybe due to unfamiliarity, or laziness of imagination).
