“We had to consider how to kill a part of some one’s soul and what that would look like. We were trying to create something very amorphous – abstract, but quite sinister and evil. We did some great performance sessions with Ralph Fiennes. We used his face, while he’s rolling and writhing around, to make this evil Horcrux creature. The idea is that the Horcruxes create themselves out of the surrounding environment, and in this instance it was dragging a lot of the dead, mold and detritus from the bottom of that pond, literally forming itself out of what was around it. Inside the liquid, we created faces that were almost pushing through. The inspiration was the self-portraits of Francis Bacon, which are very distorted, abstracted versions of himself. We took that idea and used abstracted versions of Voldemort and wove them into this massive, swirling evil. The faces in there are driven by Ralph Fienne’s performance, but then they’re being distorted and twisted. It’s pain, it’s agony, it’s excruciating. He’s having his soul ripped apart. The idea was to avoid an obvious creature and give a suggestion of an emotion more than anything else.”

Part two is pretty monumental. There’s over 20-some minutes of fighting and aerial action, but the dragon in Gringotts is great. It’s a different dragon than we’ve seen before. This is a badly, maltreated dragon who’s been kept in the dark cave all its life. It’s emaciated. It’s partially blind. It’s very, very dangerous. It’s a great character, but you’ve got to get the three kids on top of it and then they escape from Gringotts on the back of it.
But of course the main thing is the fight back at Hogwarts. The whole sequence is a roller coaster from when Voldemort arrives. It’s just non-stop action. It’s going to wow everyone.
