Acting is a KIND of self-hypnotism.

The actor:

completely convinced he or she is the character. "Sheriff, nurse, etc."

Actor has to buy the story.

Actor convinced he is in a room, no audience

It's all believing your imagination, hypnotize yourself.

           Human will is great, you can hypnotize yourself. Just mesmerize yourself with thinking of one thing, your objective.

           Complete sense memory.

"In the end, it can't look like acting."
