The American actor is very lucky. Why? Because so little is asked of him.
Don't be an actor. Be a human being who works off what exists under imaginary circumstances.
Technique is something that you use if you need it. Otherwise, to hell with it.
You don't pick up cues, you pick up impulses.
Your acting will not be good until it is only yours. That's true of music, acting, anything creative. You work until finally nobody is acting like you.
With a developed imagination there's no place you can't go.
