Die Tur or The Door with Mads Mikkelsen is worth a look. As a (partly) time travel movie, its not quite as tricky as Timecrimes and more than straining the mind with how things fit together, it plays with the emotional ramifications of doubles. That is, if you came from the future and replaced your present self, would you be yourself, or a copy?
Mads is always a pleasure to watch even if I am really waiting to see him in Valhalla Rising. But not to discount this film too much, its an unusually humanistic film for this sort of thing. (And oddly enough just after having seen AntiChrist, it also starts with the death of a child while a couple is having sex. The stand up against the wall sex scene is distinguished by the woman smoking throughout it).
