The Leaky Cauldron has posted part six of their visit to Leavesden Studios last year. This piece includes an interview with Robbie Coltrane and an excellent description of the Great Hall from the Harry Potter movies written by Leaky Cauldron staff member Melissa Anelli.
"You hear him talk about the film and he just lights up. He’s so childlike. He’s a big kid at heart."
That "him" is Alfonso Cuarón, who is hopping around the set, directing. After we were through touring we returned to the Hagrid's hut set, where filming on the hug/no-hug, finding of Scabbers, executioner-arrives moment was still going on.
"I think you owe someone an apology!" Hermione protests while Ron is exclaiming over his reunion with Scabbers.
"It's all right," Ron responds. "Next time I see Crookshanks, I'll let him know."
"I meant me!"
"Brilliant, brilliant, brilliant!" you can hear Cuarón enthuse when the take is called a cut.
Some of the interview with Robbie:
What does Cuaron bring to Harry Potter?
He's got a different style of shooting. I mean you'll have to ask him but I know he was very keen to get it out of the studio, because it was very studio-bound. That's the trouble with anything which essentially has lots of bits which are physically impossible. You're stuck in a studio. And that has to change, you're making a movie, you want to film on a movie, you want to make a mood. And I think he's been very keen to do that.
Hagrid has a larger role here because he teaches now.
Yes, he's a professor, which is quite funny. We had a lot of fun with that because the kids are kind of enjoying the fact that Hagrid doesn't quite know what he’s doing, because he hasn't done it before, so there's a lot of, "How am I doing?" and "You'd better do better." He's not really quite sure what to do.
