❝ NC: What [did you bring to Lucius’s] personality and his relationship with his son Draco?JI: I saw my role originally as first of all, to try and make him real, because these are fantastical characters, I needed to find a way to “believe” in the separation of races and racial and genetic supremacy. You don’t need to look very far, unfortunately, in the modern world to hear people standing up on platforms spouting that kind of filth. And then secondarily — maybe more important in the story, and particularly now that I see where it ends by the time we get to the end of “Deathly Hallows” — is to explain how Draco turned out to be who he was. Because in many ways, to me, Draco is the hero of the whole saga. I think Harry has his destiny. There is only one choice Harry can make in every situation. Harry makes the right choice always, and he’s admirable for doing so. But Draco has a bunch of choices, and Draco has to break the bonds of the shackles of his past. He has to break the chain of this kind of abuse and hatred and selfishness and entitlement that his father has been part of, and probably his grandfather and stretching back for generations. And so I saw my job as trying to illustrate how you end up with a kid as messed up as Draco. In “Chamber of Secrets,” I just tried to bully him as much as I could, and be as unloving as I could. And in every opportunity, I wanted to be the kind of father that was so selfish and so egotistical and narcissistic that I would happily sacrifice my son and/or my relationship with him for status. So that was the main point, was to try and explain Draco and make his decision that much more heroic, to try and do the right thing.
