Adrift (1969)

aka's: Touha Zvaná Anada/Desire Called Anada/Hrst Plna Vody

A fisherman (Rade Markovic) saves a woman named Anada (Paula Pritchett), adrift from drowning in the Danube river. He then takes her to his home and allows her to stay. Eventually he commits adultery with her, but his wife (Milena Dravic) also seems to be in love with the strange young woman. (In Czech language, with English subtitles).

Production on this film was suspended in 1968, during the Soviet invasion of Czechoslovakia, because a temporary military bridge had been erected across the Danube river, right by the filming location. Production resumed in 1970 and the film was released in the U.S on July 6th, 1971.

NOTE: The picture quality for this film is a bit soft, but currently the best available anywhere.
