I could draw my copy of the book down from the shelf, but then I'd have to get up. :) Who is the person she gives token acknowledgment to, who deserved much more?
Flaws and all (and I don't think you or Charlie would disagree with what I'm about to say), in the "cultural moment" that Kael's book came out, it pretty much changed the cinema world's perception that Welles was the singular auteur of the film. HM's name is on the film as co-scenarist, but I'd wager that most film buffs figured him to be a guy who wrote a first draft or an outline that Welles then transformed beyond recognition with his magic typewriter. It's doubtful that Mank would be made today, even despite his nephew's prominence, if Kael's book hadn't set the stage for it fifty years ago. That's why I thought Fincher might jigsaw the timeline a bit to 1971 to bring in Kael briefly as a progenitor.
