I feel like if I'm going to give you a book about my dad, then I really want to give you my dad, because he is interesting and he is funny and if you're buying a book about him, I don't want you to have to sit through stuff that's not him.
I think if you play a character that is fearless, then it's boring. I think that's what was so incredible about Harrison Ford, is that he always seemed like he was never going to survive it, he's always scared, and yet he always does survive it somehow.
