I remember my very first day, I improvised a line. […] And as I turned to leave, I looked at Daniel, and I said, “Let us hope Mr. Potter will always be around to save the day.” And then Daniel, who was all of 12, stepped right up to me, looked me right in the eye, and said “Don’t worry. I will be.” A chill went down my spine. And as he did it, I thought, ‘Christ, this kid is good.’ - Jason Isaacs
