This is gross and bad, yes, but it's more likely Coppola has struggled with financing because he's infamous for difficult productions and overbudgeting and hasn't directed a hit money-maker since the '80s.
As far as I understand, they haven't personally worked together in 20+ years. And shortly before that even Disney produced one of Salva's movies. So my point is, I don't think it will effect Coppola in any way now, and the problem goes deeper than him. Money is ultimately what talks.
This is not to excuse Coppola. He's a legend yes, but I'm sure he's not a great guy.
Unfortunately, from what I can tell, Coppola's involvement with Salva went far beyond just producing one or two of his movies. Salva was essentially Coppola's protégé and the movie where the assault took place,
Clownhouse, was partially filmed at Coppola's home. After Salva was convicted, Coppola played a very active role in helping a convicted child molester get back on his feet financially by paying his legal bills and subsequently attempting to downplay his crimes in interviews by trying to claim that Salva was "practically a child himself" at the time (Salva's victim, who was blacklisted and defamed by Coppola, was 12, while Salva was nearly 30). Realistically, it's only because of Coppola's influence that Salva had any shot at a successful career getting gigs like the Disney-distributed
Powder and the
Jeepers Creepers series less than a decade after his conviction.
This is all to say, while Coppola may be a master of the craft, these are things that aren't great to have floating around out there. This situation is one that looked bad at the time, but only looks worse now, and in our current social climate where people
will look into your connections to see who you've been affiliated with at any point in the past, I don't think it's much of a stretch to imagine that Coppola's connection to a legitimate pedophile doesn't give potential investors pause. It's something that crosses my mind seeing all the tweets on my timeline recently where people are expressing incredulity that nobody wants to give Coppola money despite his illustrious filmography and relationships with multiple other big names in the industry. I just keep thinking, "well... I can think of at least one reason why."
I think some of the blame can be attributed to Coppola's reputation of being a difficult artist who is currently trying to sell what is by all accounts a commercially unfriendly project, I won't deny that. However, I would suggest that maybe the answer to the people wondering why no one is rushing to help
Megalopolis get made is that, as Salva's case has become more widely reported on in the age of the internet and social media, it's only a matter of time before people start connecting the dots to figure out who was enabling the career of a convicted sex offender and why he was able to successfully sweep it under the rug for so long.
