Memento
written by Christopher Nolan, from the short story by Jonathan Nolan
Leonard: I have to believe in a world outside my own mind. I have to believe that my actions still have meaning, even if i don't remember them. I have to believe that when my eyes are closed, the world is still there. Do I believe the world's still there? Is it still out there? Yeah.We all need mirrors to remind ourselves who we really are. I'm no different. (long pause) Now where was I?
Kudos and much thanks go to Mo for this monologue, it is very much appreciated.
