Although this film is in colour, I found myself wondering the day after the first viewing whether it was in black and white or in colour - this was probably due to the darkness which dominates most of the film. Another reviewer has written "improves with a second viewing" and he was right. Unfortunately the copy I saw had English sub-titles which could not be turned off, especially irritating because they were sometimes not just different to the French original but also incorrect. Nevertheless I would regard this as one of the best films of its genre and if you can get hold of an uncut version (amazing and irritating how people love to mess around with old films) it's definitely worth watching (twice!)
