Scholastic have emailed to let us know that they interviewed some of the Harry Potter cast for their blog, Ink Splot 16, where they talk about the films. Some snippets may be read below and the full interviews are here.

Q: What were your thoughts when you read the 7th book, like was there any scene where you thought, “I have to film this. . .”
Mark Williams: It wasn’t very nice for me having to deal with the death of Fred. And I think both of us found that a bit tricky ’cause we spent quite a lot of time in and around that area for about two days, and that was a bit unpleasant.
Oliver: Yeah, it was.
Mark: You just got to lie there! Didn’t you go to sleep?
Oliver: Yeah, I was so in character. . . It was quite strange to read it. And then when we came to film that sequence in Part 1 when George gets his ear lopped off and everything that was really cool because I had never even had a scratch filming the films.
Domhnall Gleeson: I didn’t know I was going to be in the movie, so the first thing I did was call my dad [who plays Mad-Eye Moody] and said, “Dad, you’re dead by page 20.”
David Heyman: But it was sort of an amazing thing that we were making the movies concurrently with the books. Hogwarts, for example, has changed over the course of the films as we discovered what we had to do. We were making the films and we didn’t know what was happening. On the 5th film, the 7th [book] wasn’t already out. When we were developing the script, we’d left Kreacher out. And we sent the script to Jo [Rowling], because Jo reads all the scripts, and she called me and said, “You know David, you might want to put him back in. He’s got a role to play later on.”

Q: How was your first day on set?
Michael Gambon: I was just petrified when I came in to take over [after the original Dumbledore, Richard Harris, died]. . .But you just fight your way through it and be brave for a week until you settle in.
Domhnall: I nearly wet myself. I didn’t, but. . .I was really, really nervous. But it was really lovely. Everybody was incredibly welcoming. And you can tell the new guy on set, well, if it’s me, ’cause he’s got a wand in the corner going like, “Pew!” doing the sound effects. . .It was amazing though.
James: I can remember our first day. We learned that’s it’s not all shot in order, so our first scene was the last scene of the first movie. But I can remember being more nervous than I have ever been and probably ever will be. And we were in this little place called Goethland, in the middle of Yorkshire, like on Sunday morning, the sheep walk down the middle of the street kind of thing. I can just remember being like, nervous.
Bonnie: I remember starting on platform nine and three quarters, in the first film, and it was freezing winter. And I remember actually being the age of nine and three quarters on platform nine and three quarters. And I remember being absolutely freezing from nerves and clutching hot water bottles between every take. And I just didn’t know what any word meant. You know, “action, cut and rolling and speed,” all those words. . .I was just like, “What is going on?” I was so confused. In the film you have yet to see, we jump forward in time and we have Lily Potter, [Harry and Ginny’s daughter], and she was the same age as me when I started and we were on platform nine and three quarters, so it was very surreal going around in that whole cycle, that I started at that age and she started at that age, yet I was playing her mother. It was very bizarre.
