Still would not trust the current crop of actors/directors to take it on. Asking for a major let-down imo. Also very few people, except OLD die-hard pool nuts, would have any idea what its about. You're talking about a prequel to a 60yr old movie. Don't see it working. A new pool-themed movie? Possibly but i'm not holding my breath for anything remotely worth watching. Remember 'Poolhall Junkies'? Pretty bad.I'm not talking about a sequel, I'm talking about a prequel on Minnesota fats. It would have nothing to do with the actual movie The Hustler, it's a standalone story.
Prequels are very popular hence all the interest in the one right now surrounding The Sopranos and the popularity of Better Call Saul. The audience after they see a story want to know more about these people before the story, how did they come to be.
