George (Alain Delon) awakens in a hospital. It seems he was in a bad traffic accident and nearly died. His wife, Christiane (Senta Berger), was apparently unhurt. After a long recovery, he is sent home to his mansion--a place he doesn't recognize. In fact, he doesn't really recognize his wife! What gives? Was the accident THAT bad or is something going else afoot? Unfortunately, the more he starts to remember, the more his life might be in danger! Which isn't a surprise, since the film is entitled "Diabolically Yours"!
This film directed by Julien Duvivier is one giant mind game--on both George and the audience! All during the picture, like George, you are wondering what's really happening and who can be trusted. I like this sort of paranoid film--and it kept me guessing, that's for sure. And, considering how few films manage to do this to the viewers, I really appreciated this film. Interestingly, the film could have worked well either way--that George really is crazy or that some bizarre conspiracy is occurring. Either way, the film is great and I strongly recommend you see it. And, based on its IMDb score, I'd say this was was underrated.
By the way, this film has some similarities to the Hollywood B-movie "My Name is Julia Ross" as well as an earlier Delon film, "Joy House"--both are also well worth seeing.
