Spoiler AlertIn the scene where Sirius dies, Dan Radcliffe's scream of anguish was so intense that director David Yates didn't want to put it in the film because he knew young kids were going to see it. Instead he opted to play the moment with no sound, just sad music. Personally I wish he had kept it in. I'm a big fan of Dan's acting in Order of the Phoenix and it would have been a great moment.
Ah, heck. Why not have another one today?
HARRY POTTER AND THE ORDER OF THE PHOENIX (2007)In the scene where Dumbledore's Army is being chased through the Hall of Prophesy by the Death Eaters none of the shelves holding the prophesies were actually there. There was just green tape marking where the shelves were and then they were all added digitally later. There were a lot of unusable takes because the actors were running so fast that they kept running into where the shelves would be.
