Btw just finished watching the Hitchcock movie, The Rope. It was filmed with only 10 cuts when they were forced to because of camera limitations. The camera seems to become you as an unseen actor. It happens in real time after a murder. If anyone hasn't seen it certainly give it a watch.
It's genius in it's subtle simplicity yet the suspense builds each moment. Hitchcock was truly ahead of his time.
Sarcasm with style!
Using the old saying, "What you don't know can't hurt you," he's practically invulnerable.
