La demoiselle d'honneur (2004)

English title: The Bridesmaid.

A young man falls in love with a nutsy young woman, who says four acts are required from lovers in order to "prove" their love to each other.

This is like a slow-paced "Alfred Hitchcock Presents" episode, and has been smartly (and perhaps too severely) criticized at the "Hated It" section of IMDb's User Comments. One thing is sure, insanity -- because it allows for reckless behavior from the protagonists -- attenuates suspense, and identification. But there are interesting things in it that sort of make up for those absences. The film can perhaps best be savored as a psychological study of the oedipal character. One may notice points of contact with classics such as Rope and Strangers on a Train.
