Here's the meaning....

Rating: Null/10 (2 May 2018)

The entire movie from the aftermath of car crash to the opening of blue box is not real. The couple at the beginning are strangers she met on a train. Their laughing represents what people say about a failure. The waitress with the tag of Betty either signifies her failure from acting and the eventual waitressing for sustenance or just the source of inspiration of Betty for her dream. Maybe Camilla and Rita of the end are the same person, maybe not, doesn't change a thing. Not really sure what the black figure symbolises, maybe the blacknes if heart of the Hollywood industry in general which is not easily seen. The party sequence at the end is THE most important sequence to understand the whole movie, which is about the lives of newcomers who try to break into the Hollywood scene.
Very good direction. Truly exceptional.
