An actor doesn`t change thought, theme, or mood unless the character does, and the character only does it within the words of the play.
I`ve always played disintegrated characters.
Once you`re on (stage), nobody can say, "Cut it". You`re out there on your own, and there`s always that thrill of a real live audience.
(about Arthur Miller`s semi-autobiographical play "After the Fall") They should have called it "After the Money"!
The theatre has kept me alive, and it`s allowed me to work at my craft.
All I know is, I don`t do a lot of analysis. I know those words have to move me. I rely on the author. I don`t want actors reasoning with me about "motivation" and all that bull. All I want `em to do is learn the goddamn lines and don`t bump into each other.
