REVISITING 20 YEARS LATER: "How can you be nearly headless?"
I noticed this almost back when I first saw it in 2001, but Harry is absolutely new to the Wizarding World and everything about it in general when he first enters Hogwarts, yet when Hermione asks this question of Nearly Headless Nick, he ROLLS HIS EYES at it, yet still reacts in a horrified manner when Nick pulls off his head, stopping short of some uncut flesh on his neck holding it on.
Why did the filmmakers allow that eye-rolling reaction in?
