I was probably more scared of my high school exams than I was of the Oscars. At the time you think it's everything and if you don't do well, your life's over. Opportunities are gone. So the more you do it, the less the fear is present.

One of the Canadian customs guards got suspicious and said 'Haven't you been coming and going across the border a lot lately?'
