I was drawn to the 1960 French film Eyes Without a Face, directed by Georges Franju, by the names of Boileau and Narcejac. They worked on the script, but it was in fact based on a novel by Jean Redon, of whom I really know nothing. A bit of research suggests that the original book may have been rather pulpy and that B and N added more sophisticated elements.
It's a film about a number of murders, but it's widely described as a horror movie, and for good reason, even though that label does not adequately convey the strangely lyrical nature of many of the scenes. Suffice to say that it's one of the most chilling and disturbing films I have ever seen.
When the film first came out, it was only a minor success and some critics and audiences were appalled by it. More than half a century later, it's been re-evaluated, and its excellence is now very widely acknowledged. Briefly, the story concerns the attempts of a plastic surgeon to reconstruct the face of his terribly disfigured daughter - played, quite brilliantly I thought, by Edith Scob. The doctor is assisted by an equally obsessed woman whose face he had previously restored.
The direction is excellent, and the score, by the legendary Maurice Jarre, makes a real impact, especially in the opening scene, when a woman is driving a car through the night with a mysterious passenger.
Choosing Boileau and Narcejac to work on the story was an inspired decision. The dialogue is sparse, but the terrible story is gripping throughout, all the way to its remarkable conclusion. Not an easy watch, but an impressive piece of work. And if anyone knows more about Jean Redon, I'd be interested to learn it.
