Quoted from the interview:
I bring up rumours that Anderson did uncredited writing on Ridley Scott’s Napoleon and Martin Scorsese’s Killers of the Flower Moon. Does he also get advice from other directors?
PTA: “I love to contribute in any way I can if somebody reaches out for help. Both of those things were a thing with Joaquin [Phoenix], a thing with Leo, and obviously with Marty and Ridley. It’s always a privilege to say, ‘Let me tell you my thoughts on the script.’”
- He cites his friendships with three late directors in Robert Altman, Jonathan Demme, and Robert Downey Snr. “They made me feel encouraged and confident.”
