"Me act? Why, I just make faces! Really, that's all I do, I make lots of faces and they pay me for it. The director says: "You're mad, Peter. Make like you're mad.” Then pretty soon someone calls out “one hour for lunch”! I follow the others to the commissary and later return to the set. "Make like you did before lunch, Peter," says the director. "Make like you're mad." So I make like I'm mad again and before long someone says, "wrap 'em up. That's all for today." So I go home, have dinner, go to bed, get up, report for work again and the director says: "Make like you're mad again, Peter. Make like you did yesterday." I find it so easy. I just look mad and like old man river I keep rolling along doing devilish things in motion pictures."
