In addition to Bonnie Wright and Evanna Lynch, we have the interviews that Matthew Lewis, Tom Felton and Rupert Grint did with Total Film Indonesia.  You can read all the interviews at the links on their names.  You can see the scans below and some segments from the interviews.

You start as a bully and end up being one of the more complex characters.
Tom Felton: Yeah, it’s a real journey, I think, for young Draco. I think Jo [Rowling] – I mean, I don’t know this for a fact – but I think he was written purposefully quite one-dimensional for the first five years as sort of a typical bully… to get the audience hating him, to get the audience knowing exactly what he is. And then on the sixth, we sort of go behind the scenes a bit and see his family, to meet his mother, who I think is a good representation of why maybe he was a bit softer than his dad. His dad is certainly more militant… he also bullies him to a small extent so that’s half the reason I think, why Draco is how he is. It’s been fantastic for me as an actor, really, to sort of play it one way and for it to be turned on its head and to completely go the other way with it… I was actually very nervous about the lack of stages of the character because I knew it was going to get a lot more complicated and I wasn’t really that confident in my ability. But David Yates set up several meetings to boost up my confidence and he’s really happy at the end of it.

Neville’s so heroic in the end, which is wonderful, so what’s your definition of a hero and who is your hero?
Matthew Lewis: Well, the Leeds Rhinos [his favorite rugby team] were my heroes, last night! I don’t know if you caught the game; they were unbelievable. But no, my real definition of a hero is… obviously, all the people who are in the Middle East right now. You know, those guys are the heroes. I don’t personally know anybody who’s out there, but I know friends of friends that are and it’s shocking. It’s wholly shocking that in the twenty-first century, that sort of thing still goes on. Those guys are out there, doing a job, and they don’t wanna be there, but they are, and I think that’s courage and heroic.

This time they’ve given you more deep, emotional stuff. How hard was it to do Ron’s jealousy and falling out with Harry?
Rupert Grint: Yeah, it was good. It was, I suppose, a different kind of side to Ron in this film. We don’t really see Ron kind of, um, turn against his friends that often. He really does have doubts with Harry’s ability and the fact that we’re not really getting anywhere with these Horcruxes kind of fuels that. He’s a bit jealous, as well, because he sees Hermione and Harry together, and he’s just not having a great time. It kind of erupts into a this bit of an argument. Those scenes are really quite good fun, actually. Whenever me and Dan are shouting at each other… it’s always great.
