I was a precocious only child and then I went through a fat awkward stage for several years so I learned to fall back on my humor and personality when I was growing up. It's how you survive so I think it was more of a natural progression for me developing into comedy.
It's up to the courage of the filmmakers to make art in cinema not just business. John was rejected by studios he borrowed money and did movies with his own money. You're either courageous or not. You have to find a way.
