Here's a bit of interesting info that most of you are probably not aware of . . .
That idea of the hat came from the storyboards drawn by Mike Ploog(my fave comic-book artist of all time) . . . he of "Werewolf by Night", "Man-Thing", "Ghost Rider", "Frankenstein", "Planet of the Apes" et-al fame.
From page 237 of the hardback "The Art of Ploog" (December 2015) . . .
My admiration for EVERY SINGLE PERSON involved in the creation of this movie is so off-the-charts, it's almost embarrassing to admit (almost - but I still do it ).
If I'd been one of the producers, I could not have made better choices.
Everything about this film is perfect, and it will FOREVER stand the test of time as an absolute classic.
