It is no secret that this is a classic suspense film in every sense. It would seem only natural that Criterion would pick this film to be part of their revered collection. Most people who are willing to spend the kind of money that it takes to acquire a Criterion disc take comfort in the knowledge that they will experience the highest possible picture and sound quality possible for the particular film. Well, with the disc of Diabolique, that is just not the case. The film is loaded with dirt, grain, holes, tears, and even splices. At one point in viewing the disc I noticed a large circle flash by. I scanned back and paused on the frame to see that what appears to be a melted spot on the film had been circled, perhaps for removal later. It is still there, though. Also, the picture had a slight vibrating quality about it through the whole movie which was an annoyance. The picture is watchable, but for the price and the Criterion name, I expected much, much more. There are some serious issues with the sound as well. There is a constant low hiss on the soundtrack that can be distracting. The subtitles are pale and hard to read. I always enjoy watching the restoration demonstration on Criterion discs. I like seeing how huge picture defects can be erased just like magic. This movie obviously never recieved such treatment. I find it hard to believe that any restoration work at all was done to Diabolique before it was dumped on the market. Basically, the movie is definitely worth seeing, but do not assume anything simply because this is a Criterion disc. You could buy the same movie of the same quality on VHS for much less.
