"Last night, when I was watching Susan, I remembered another trivial moment when I was watching her film a scene in "TOP SECRET AFFAIR". It was a bedroom scene with Paul Stewart. The Director had to call "cut" because Paul Stewart forgot his lines. While Stewart was reviewing his dialogue, Susan sat down on the edge of the bed and proceeded to go through some facial exercises (yawning, filling her cheeks with air and blowing out the air). I guess she did this to relax. It is funny how all of a sudden I remembered this detail".
