“Neville helped me grow up as much as he’s helped people who’ve watched the films. When I first started, Neville and I were very similar: shy, chubby-faced boy. There was very little acting in the first couple of movies. That’s just me. But as he grew, so did I. And the thing about Neville is this amazing message that J.K. Rowling did for him. This message of evolution. Neville’s bullied, he’s scared of his own shadow. No one ever thinks he’ll amount to anything. And here he is in [“Deathly Hallows — Part 2”] saving the Wizarding World. It just shows you that, no matter how your childhood is, it doesn’t define you.”
