Director: Alain Robbe-Grillet
The late-60s after the Nouvelle Vague was a glorious time for self-reflexive films featuring cool young people shot in rich black-and-white, involved in glorious intrigues in European cities with a smattering of s&m themes. Which is what Robbe-Grillet's film does, though at a rather higher level than my glib summary.
It was banned in the UK at the time, but time reveals that Robbe-Grillet's film has aged well. The b0ndage themes are somewhat perplexing, and the s3xual politics in general are of the era, but the playfulness of the narrative construction -- Robbe-Grillet himself dictates the story from a train carriage, while Jean-Louis Trintignant's character wanders by -- remains fresh and the lucid cinematography is still lustrous.
I'm afraid I can't say much more, as I've contrived to allow a whole month slip by before writing it up...
