Disney was an artist who became a mogul. That was rare back then. They mostly were businessmen. This movie tries to analyze whether he can go back to being an artist, the one who created Mickey Mouse. I appreciated that the script was originally developed outside the walls of Disney. Walt wouldn't seem like a human without flaws. No Scotch, no cursing. And that he doesn't invite Travers to the Los Angeles premiere.
We know Travers was not invited to the premiere. She invited herself. She did not care for the movie. She went to Walt afterward and said we have some work to do and he told her, "That ship has sailed." We also know that she cried during the movie. People who knew her have said that those tears would not be the result of her hate of the movie being so great. What if the reason she cried was not about the movie at all. What if it was the end of a cathartic experience? Coming to terms with her life as a little girl and her father?
