Theatre is more exciting in the sense that you can actually see the audience in the eye. You know there are no takes and retakes. You have one chance to do your job... and you better do it well!
At 15 I auditioned for 42nd Street in Australia. Dein Perry was in that show. I actually got the job but I couldn't do it because I was only 15. Legally I needed to have another 15-year-old to cover consecutive nights.
