My view of actors is that basically they're all harmless lunatics who'd be on the psychiatrist's couch, except that we get this sort of catharsis every six months or so, and we go and be absolutely someone else.

People have this idea that the more pious and devout I am, the more successful I am. Which is very dangerous. If you look at faith in that way, you're bound to fail at both - spiritually and in your career.
