Daniel Radcliffe: They all know that the reason they’re on this journey to destroy horcruxes and Voldemort is much bigger than any one of their individual lives.

David Heyman: They need to destroy Voldemort to make it safe for the wizarding world. They know that the horcruxes are the key.

David Barron: Voldemort is terrified of dying and he’s gone to incredible lengths to ensure that he stays immortal.

Emma Watson: Voldemort has split his soul into seven pieces. He’s hidden these seven pieces of his soul in different objects that are related to his past and related to him and who he is. Harry’s already destroyed the diary; Ginny Weasley’s diary had a piece of his soul in it. Dumbledore destroyed the ring, so that’s two.

David Barron: The locket, that’s also destroyed, so they’ve got four horcruxes to find and destroy.

Ron Weasley: (in the Lestrange vault) Is it in here Harry? Can you feel anything?
David Yates: Harry, Hermione and Ron suspect there’s a horcrux in Bellatrix Lestrange’s vault. Harry has a special affinity with horcruxes. So in this mountain of stuff, it’d be really impossible to find anything. But Harry can tune into these things.

Ralph Fiennes: Voldemort knows that as each horcrux is destroyed he loses his power and actually is diminished to nothing.

Harry Potter: (to Ron and Hermione) He knows if we find and destroy all the horcruxes, we’ll be able to kill him.
I reckon he’ll stop at nothing to make sure we don’t find the rest. There’s more. One of them is at Hogwarts.
Daniel Radcliffe: As Harry starts destroying parts of his soul, Voldemort starts slowly losing his mind.

David Yates: I want to explore the vulnerable side of Voldemort. His fear. His anxiety. The things that make him the monster he is.

Ralph Fiennes: Once he realizes Harry is on to his secret, then there’s a sort of urgency.

Emma Watson: It’s a fight against time becauseVoldemort’s attacking the castle and they don’t know where it is and they’ve got to try and find it before he gets in.

Harry Potter: (to Dumbledore's army students) There’s something we need to find.
Something hidden here in the castle, and it may help us defeat You-Know-Who.
Emma Watson: Most of Hogwarts are trying to hold them off.

Professor McGonagall: Do what you have to do. I’ll secure the castle.
Emma Watson: There’s this epic battle going on while they’re trying to destroy the last horcruxes.

Rupert Grint: This is it, really. This is kind of the end of the line.

David Heyman: Harry knows very clearly that he has to finish his mission. If he doesn’t find the horcruxes then there is no hope of victory.

Daniel Radcliffe: This is Harry’s last chance to finish this once and for all.
