Superman III (1983) / Superman IV: The Quest for Peace (1987)

Superman III:
After Superman: The Movie's epic storytelling and Superman II's awesome battles, how could the first two hits be topped? In Superman III, meet Gus Gorman (Richard Pryor), a half-witted computer programming natural. For him a keyboard is a weapon and Superman faces the microelectronic menace of his life. Christopher Reeve reprises his most beloved role, deepening his characters human side as Clark Kent reunites with old flame Lana Lang (Annette OToole) at a Smallville High class reunion. And when Superman becomes his own worst enemy after Kryptonite exposure, Reeve pulls off both roles with dazzling skill. Incredible visual effects abound but above all it has heart, heroism and high-flying humor. All in superabundance.

Superman IV - The Quest For Peace:
Christopher Reeve not only dons the title hero's cape for the fourth time but also helped develop the movies provocative theme: nuclear disarmament. For me, its the most personal of the entire series, Reeve said. It directly reflects what Superman should be, and should be doing. Superman does a lot this time around. To make the world safe for nuclear arms merchants, Lex Luthor (Gene Hackman) creates a new being to challenge the Man of Steel: the radiation-charged Nuclear Man (Mark Pillow). The two foes clash in an explosive extravaganza that sees Superman save the Statue of Liberty, plug a volcanic eruption of Mount Etna and rebuild the demolished Great Wall of China.
