a member from snitch sneeker saw dan radclff at times talk in nyc this is what he had to say about hbp

- Dan said that of the Half-Blood Prince move from November 2008 to July 2009, he was told about it 24 hours before the rest of the world, and begs everyone not to blame him for the move.
- About Half-Blood Prince Dan says that the parts with Dumbledore and Voldemort are the darkest, while the scenes with Ron are the funniest yet; he also mentions that Jessie Cave (Lavender Brown) was really great to work with.
- Dan talks about a particular incident on the Half-Blood Prince set, where Rupert had his first kiss with Jessie, and Dan was in the background of the scene laughing and trying to get Rupert to break out from character and laugh as well.
- Dan addresses how Emma Watson was hesitant about signing up for the final films, and her reason for doing so was not because she did not want to, but because of her education and the need to evaluate what her options were, especially since the last Harry Potter films would require another three years of their lives. Emma chose not to rush into the decision, but her reason was not because she did not want to.

If Emma leaves the cast..every harry potter fan will hate her and throw stones at her if they see her. They'd have to replace Hermione with some other actress..and that would VAMPIRE! up everything! What a bittchh if she quits!
