Released in 1980, “Superman II” is a sequel to the super popular Superman I, and it was also followed by Superman III. They really nailed the numbers on these. Superman 2 continues the Man of Steel’s adventures as he battles Kryptonian villains including General Zod amidst the growing popularity of superhero films during the late 70s and early 80s. Superman II definitely raises some questions though. Like where did Marlon Brando go? Why didn’t Lex Luthor just shut his lights? Why are snake bites so painful? Why did Superman have to give up his powers and then get them back so easily? What was with that cellophane S? To answer all these questions, check out the pitch meeting that led to Superman II.
