Not Hugging Boys
In the early days of filming, Emma Watson was quite shy, and so she was a little too embarrassed to hug her male co-stars, so we don’t see her hugging the boys during the final Great Hall scene. We only see her at the end of the movie hugging Harry before looking very embarrassed and then subsequently shaking Ron’s hand.
Arthur Weasley’s Fate
While every fan of Harry Potter knows that Harry’s godfather Sirius Black is tragically killed in Harry Potter and the Order of the Phoenix, did you know that it was Arthur Weasley who was supposed to be killed off at first? In the end, J.K. Rowling decided to spare Ron’s dad and eliminated Sirius instead.
