I remember standing in the elevator, waiting for him to open it, and all of a sudden I panicked because, as I heard the footsteps coming to the door, I realised, "Phil, when that door opens it's going to be Robert De Niro. It's not going to be your dad or your brother or something, it's going to be De Niro." I started panicking, my heart started racing. Actually, he's patient. He works very hard physically.
