LIVE POLL: Thinnest Veiled Real-Life Fictional Movie?

The industry term, cinéma à clef, translates from French to English as "film with a key". The key being a listing that is used to swap out the names of real-life people with their movie character aliases. These stories depict a heavy dose of real life characters and true events, somewhat hidden behind the facade of fiction. However, sharp movie-goers will quickly discern who the fictional story really portrays in many cases. Thus, the end-of-the-film disclaimer stating "This is a work of fiction. Any resemblance to actual persons, living or dead, or actual events is purely coincidental." is very ironic. These quasi-biographical movies are never 100% accurate, but their thinly veiled stories mirror real-life historical details enough to blur the line that separates them from true story biopics that often also take liberties with details to enhance the dramatic effect of the story.
