Earlier this week I posted that OOP movie director David Yates said that in the original draft of the screenplay for OOP, they had decided to remove a character from the story. Rowling read over the screenplay and said “I wouldn’t do that if I were you,” that they were free to do whatever they liked, of course, but “if you make a 7th movie you’ll have tied your hands.”
Well, today the mystery character was revealed. Knowing who it is doesn't give hardly anything away, but don't click on the link if you don't want to know....
But I wonder what essential part he has to play? Maybe unwillingly helping Harry to find the real locket? Maybe stabbing him in the back with a heavy sword? (See this post.) Maybe something random that no one's thinking of?
See what I mean? Knowing doesn't help at all.
