One key moment is when Barton talks to his hotel neighbor, Charlie, who turns out to be much more than he first seemed. This encounter makes you question what’s real and what isn’t in Barton’s life.
Some fans think that Charlie might be a version of death or even a manifestation of Barton’s guilt and inner struggles. What if Barton was meant to write not just for Hollywood but for something bigger, but he just couldn’t see it?
An alternate ending could show Barton finally completing his script, but at the cost of losing his mind. A prequel might reveal how Barton became so obsessed with art and storytelling, showing us the beginning of his strange journey to Hollywood.
