Coming Soon has a new interview with David Yates.

CS: And these are all new sets and locations? Because the first six movies have all been at the same Hogwarts sets just redecorated and dressed differently.
Yates: Yeah, yeah, and this time we’re out on the road and then we come back to Hogwarts, but the difference is we trash it. We blow it up. It turns into Stalingrad, which will be really haunting.

CS: Are you actually going to blow up Leavesden Studios when you’re done there?
Yates: (laughs) I’m not sure they’d be too pleased with us if we did that, but we’ll probably end up blowing up half of Leavesden. I keep saying to the special FX guys (that) these things are going to be big. We have to go out with a bang.
