Unlike me, a lot of child actors are very short, which is why they work. So when they're 15 they can play 11 or when they're 18 they can play 14. They look young for so long, they have abilities a much younger kid wouldn't have. ↗
By the time you get dressed, drive out there, play 18 holes and come home, you've blown seven hours. There are better things you can do with your time. ↗
Every little thing that people know about you as a person impedes your ability to achieve that kind of terrific suspension of disbelief that happens when an audience goes with an actor and character he's playing. ↗
