“[I was surprised] how much I thought I had in control and how little control I actually have,” he told PEOPLE at the Toronto International Film Festival. “I have none! I think everybody quickly realizes that.”

“My daughter looks exactly like Amal,” he said. “She has big beautiful eyes … It’s incredible.”
