"The Aviator" [1] about Howard Hughes? Love to also talk about real startups movies without failure as a main theme. For example, "The Social Network" (includes Winklevoss and Eduardo Saverin "failures"). We have other non-fictional ones such as "The Founder" [2] about McDonalds. Classic: "Pirates of Silicon Valley". Ford v Ferrari (amazing if you have not seen it) [3].
And what about "Citizen Kane" [4]? The Fabelmans, Steven Spielberg's biography. Have not watched entirely the last ones about Steve Jobs, I don't think they captured the real character and complex personality.
Bigger lists tagged startup in IMDB [5] and company [6]. Most of them are based on fiction.
