In planning my Listening Room, I watched "Making of Disney's 20,000 Leagues Under The Sea" and learned about Peter Ellenshaw. He painted glass placed in front of the camera to enhance the environment, creating a seamless in-camera visual effect.
Having flashback to 70's episodic kids shows like "Land of The Lost" as I watch bounty hunters try to catch a SLOWWW running little girl (Princess Leia) in OBI-WAN-KNOBI. Disney almost had me stay longer after recognizing FLEA, but I'd rather mow my lawn.
