I think education is one of the greatest tools for most kids not only to expand their book knowledge but their ability to experience new things - I think it opens more doors than any other experience I can think of.

It's a wonderful profession and it opens lots of doors and I think it's quite right that people can accuse actors and actresses of being dilettante but you learn on every job whatever it is the process moves you on in some way and yeah I want to expand my knowledge of our existence I suppose.

Our knowledge is a receding mirage in an expanding desert of ignorance.
