Idea: film in an elevator.
The doors opening and closing would serve as bookmarks to my short film. It could serve as a kind of confessional space, a place where your internal thoughts could be expressed (in your head). A place of internal reflection? Could get some interesting angles and reflections (if I shot in one that had a mirror). Could be quite claustrophobic and awkward and add to the disconnected/awkward/strange feeling I want to be in the shots.
