There may be something to the rumor about Paul Thomas Anderson having rewritten significant portions of Killers ot the Flower Moon, at least during the later stages. After reading a Charles Bramesco tweet that passed along the PTA rumor, I checked with a person with ties to the KOTFM show, and he didn’t pour water on it. He called Anderson “an artist” and said “anything he may have done [rewrite-wise] could have only helped.” That’s a little vague but it’s certainly not a blanket denial.
Jordan Ruimy update: “I don’t want to name names here, but two sources of mine, one of which worked extensively on Scorsese’s film, are confirming Bramesco’s claim — PTA did, in fact, take part in rewriting a good portion of the script. There might, or might not, be a few trades reporting on this soon. If I was able to corroborate it then it’ll be very easy for them to do the same.”
