SPIOLER: This episode seems to take inspiration from Superman (1978): Orville was based on Lex Luthor's Henchman Otis from the Superman movies, Lex Luthor had a secret underground lair in downtown Metropolis, and Superman, in the Supermobile, spins around the Earth to get rid of the Sun Creatures.
Lex Luthor next appears in animation in a commercial for Sunnyland Refining Company Superman Peanut Butter.
