In a new interview with MTV David Heyman has discussed Deathly Hallows being in 3D!

MTV: When did you make the decision to do the two parts of “Deathly Hallows” in 3-D?
David Heyman: I think that it emerged organically. Clearly, the success of 3-D movies has had an impact on the economy and making of films. We saw an opportunity and grabbed it. Also, “Harry Potter” itself has so many exciting possibilities for 3-D, both in things coming at you and also just in making that world seem even more epic than it already is. “Harry Potter” is already an epic film, but having that added dimension will make it even more epic, and that seemed like an opportunity that was too hard to pass up. Though we didn’t shoot it in 3-D, the quality of post-3-D has improved remarkably in the last year or two, so we felt very comfortable with that process.

MTV: Is there one scene in particular that you think is going to be especially great in 3-D?
Heyman: One of the things I really loved about watching James Cameron’s approach to 3-D in “Avatar” was that it wasn’t about things coming out at you all the time. It was actually about adding great depth. You wouldn’t want to overuse stuff coming at you. We haven’t begun the process of converting it yet. We are doing some tests and looking at various things, but we aren’t done with any sequence yet. I am obviously looking forward to some of the battle sequences in the second part. I am also looking forward to seeing the dragon flying up. I think there’s a lot that will be great in 3-D, but to me, where it’s really most exciting is just making that world seem much deeper, richer and what that extra dimension gives you.

MTV: Now that you’re going to do “Deathly Hallows” in 3-D, have you given any thought to re-releasing some of the other “Potter” films in 3-D?
Heyman: Those discussions haven’t yet happened, but I’m sure it’s just a matter of time. You know what? I actually shouldn’t say that. Who knows? It would be great. You can never tell. I hope so.
