Michael Mayer, who co-wrote and directed "American Idiot." Meyer on Green Day's reaction after seeing their first rehearsal of the show: “It was the first time they heard characters singing their songs or a female voice doing their material. It was terrifying. I remember being just a nervous wreck. I was sitting at a table facing the actors. The band was alongside me so I couldn't see them. “At one point one of actors gave me a thumbs-up. I looked over and all three of them were sitting there with tears streaming down their faces, which I will never forget. It was one of the most satisfying moments in my life.”
