I own a copy of My Lunches with Orson and can confirm it's a fantastic read. Not everything Welles says is strictly true, of course -- he was a legendary self-mythologizer, and here what he's saying is getting to us filtered through Jaglom as well -- but he certainly seems like a guy it would have been fun to have lunch with!
Like others, I recommend absolutely every video of this channel. They were eye opening for me about the ways film makers use to make us feel emotions. And when they had nothing else to say, they just stopped instead of pumping out lesser essays, like some others would do (and did).
The only thing coming close in terms of quality for me is Chroma, but it's French so not known at all in the English speaking internet world.
Jackie Chan once credited Buster Keaton as an influence on his own acting and film making, which, in my book, makes him a cultural-epochal appropriator. Late 20th century Hong Kong film actors must not be allowed to imitate or mock early 20th century Hollywood silent film actors.
Progress gets made by people imitating what other people do and then modifying it. If this gets labeled as cultural appropriation then we should just stop any kind of progress. I am sure Keaton got his inspiration from predecessors so he is probably an appropriator too.
