 As an in-joke, Pattillo named Lady Penelope's alias, Wanda Lamour, after APF puppet operator Wanda Brown.APF had always found it difficult to make Supermarionation puppets walk convincingly, so rarely showed this action openly on-screen.Instead, the puppet operators created an illusion of walking by holding the puppets by the legs (which were kept out of shot) and moving the puppets up and down using a "bobbing" motion.
