About the new 'Pynchon movie'

One Battle After Another, the new loose adaptation of Vineland by director Paul Thomas Anderson, has gotten Thomas Pynchon's blessing, according to an interesting article at The Film Stage: 

“ 'Realistically, for me, Vineland was going to be hard to adapt. Instead, I stole the parts that really resonated with me and started putting all these ideas together. With [Pynchon’s] blessing,' Anderson notes, confirming he’s one of the rare individuals on the planet who has crossed paths with Pynchon, the reclusive postmodernist author whose new book Shadow Ticket arrives just after One Battle hits theaters."

Describing the new movie, the article says, "While the story of revolutionaries is inspired by Thomas Pynchon’s 1990 novel Vineland (moving up the events a few decades), Anderson’s film barely lifts a sentence from its source material, instead using just the basic structure to tell a story all his own."

I have not crossed paths with Pynchon (that I know of, of course) but when I read Chapter 11 of Vineland, I did wonder if Pynchon has been to Oklahoma, where I grew up and lived for any years and still have relatives; the description of Oklahoma City was accurate, and the details of the big storm coming into the city sounded like it came from someone who was familiar with Oklahoma's violent thunderstorms. I ran a couple of searches, but I can't find any proof Pynchon has traveled to Oklahoma.
