I know a lot of people work those sort of hours but I think we really feel it because most of us are young and fairly inexperienced. But I am very grateful because it is good experience.
It's like an apprenticeship, but we do it in front of 20 million people so all our mistakes are up for the world to see. Fisher transitioned to Hollywood in , with the part of the love interest of a cowardly slacker Shaggy Rogers in the live-action film Scooby-Doo.
