Remade, in English, as The Eye Of The Beholder(1999), starring Ewan McGregor and Ashley Judd. Between these two direct versions, Bob Rafelson's "Black Widow" appeared, having a very similar plot (but with two female protagonists) and giving Sami Frey a role quite similar to the one he plays here.
This film adapts from a novel by Marc Behm, an American who spent a great many years living in France and worked on the screenplays of British and French films. His novel is set entirely in the US and takes place all over that country, with a plot that spans many years. This film condenses the time-span considerably, and now takes place in several parts of Europe.
