There’s no director in existence, past or present, who was so dedicated to perfection and detail, as Stanley Kubrick. There’s no shortage of horror stories from this film, and the results speak for themselves.

He chose to shoot the film in chronological order, so he could change things along the way, and was so compulsive about everything that he drove Shelley Duvall insane. She’s so fragile and broken in the end of the film, because she actually was.

That’s not acting, that’s literally a broken woman after a harrowing 250 day shoot.
