Enduring Love, post script. . .

Actually it turns out that's not the end of the stalker (Rhys Ifans), when Joe (Daniel Craig) stabs him. In the credits, there a scene of what I assume is a mental ward. It slowly pans across a variety of inmates, and then goes into a room where a man is writing at a desk. The man stops writing, turns his face towards the camera, and smiles. Yes, it's the stalker! And THEN you start wondering about the films title, and exactly who's enduring love is the movie all about. . .
