The Professor (
Stuart Pankin) and Max, his flying robot assistant, work in their laboratory trying to produce the absolute 3D device-Real-O-Vision. It's through Real-O-Vision that Elvira, Mistress of the Dark (Peterson), emerges singing "Living in a Haunted House." But when computer crashes and mechanical breakdowns occur, Max gives us a tour of the evolution of 3D-from perspective in Renaissance paintings through to 3D films of the 1950s.
