My dad said 'The thing that I was told that was really helpful was that I mustn't be afraid of the things I was afraid of when I was five years old'. The shock of his childhood had put him in this defensive crouch against the world and he needed to know that he had a nice wife and kids and it wasn't the same any more.
Acting is fantastic but to be able to create a whole world on celluloid is amazing. It's like taking your dreams straight from your head and projecting them onto a screen.
