“Stepping into the shoes of one of the Wizarding World’s greatest wizards… Well, as an actor, I assume that Grindelwald has taken it for granted since he was quite young. Obviously, he is at the same level as Dumbledore – equal powers, equal goals of leaving the world a better place, but by different means. So, I approached it like that: as a man who thinks he has virtue on his side, just as Dumbledore believes he does.”
