I have seen movie made in the 30s and 40 where there is a bedroom scene where one character(usually the woman) is in a large bed, but the other character(usually the man) is either standing still or walking around the room. Never a scene with them in a large bed together. I wonder if the actors and actresses thought that it was ridiculous.
Remember “It happened one night” with Clark Gable and Claudette Colbert? Colbert flashing some leg to get a car to stop and pick them up? The trumpet sound when the Wall of Jericho finally came down? Hotcha!
