France's strange 2002 drama/romance with a touch of fantasy/Sci-Fi requires some patience of the viewer as it plods in parts, but your patience will be rewarded with a very different and mostly interesting movie.
Graham suffers from recurring memory loss. He may remember you for an hour or so, sometimes longer, but he most likely won't know you tomorrow. He doesn't recognize his wife, son, or best friend, except as entries in a notebook he keeps with him to define his identity. Since he can't remember his family, he lives alone.
Graham works as a photocopy clerk for a conniving female boss who uses his problem to have sex with him every day. Of course, he never remembers it. A newly employed young woman falls in love with Graham, but she is confronted with having to conquer him anew each day. To cope, she'll have to remember for both of them.
An interesting if slow-paced movie, with a slightly twisty ending.
