Director Cameo: [Lucky McKee] The man with his girlfriend in the elevator, both times.
Originally the film opened with a lengthy introduction to May as a child. But when the film appeared to be taking too long to get to its point, most of those scenes were cut. The opening with the adult May, specifically the first scene with her and her doll, were shot quickly and only to make the point that May was lonely as quickly as possible.
The scene where Blank and May meet was a re-shoot. In the original scene, May was not cold and vague, but angry, and insulted people as they walked by on the street. The scene ended with the two of them in the park. That scene is still in the film but entirely replaced and reedited. It is now the scene where Adam and May meet and have there final talk in the park. The scene is told only through close ups, with both May and Adam glancing off camera. They were originally looking at Blank who was sitting beside her. But he was edited out of the scene completely.
