If you like subtle psychological thrillers, I highly recommend the French film La Moustache. The story centers on a man who asks his wife if he should shave his moustache of 13 years, to which she replies she would not recognize him without it. After shaving and attempting to surprise her, she does not notice the change and insists that he has never had one. Learning that his father has been dead a year and his friends don't exist, he slowly spirals into an almost sensible madness that he can only escape from by clinging to the eyes of his wife. Some might find it to be unsatisfying as entertainment or smacking of French pretentiousness (not a redundancy, I remind the reader), but I think this is a very singular story, satisfying in its own odd way.
