Someone I met years ago explained to me the difference between a personality and an actor, a personality being Eddie Murphy or Roseanne Barr, and an actor being Morgan Freeman and Alfre Woodard or Marlon Brando.
The good thing from my perspective is that nobody puts any pressure on me to say what it's going to be. The backers accept that they don't know what they are going to get.
Strangers used to gather together at the cinema and sit together in the dark, like Ancient Greeks participating in the mysteries, dreaming the same dream in unison.
