It’s a great thrill as a director to see potential in somebody who hasn’t done something before. And it’s really fun when you get to raise some eyebrows with a piece of casting. People are like ‘wow, what’s that gonna be?’ when you know in your own heart, you know, it’s my job to see this potential. And I knew Harry was gonna do a fantastic job. I’ve been really excited for people to see him in the film. He does a really remarkable job of projecting truth in a subtle way and I think he’s a fantastic film actor.
