Superman III

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 character's human side as Clark Kent reunites with old flame Lana Lang (Annette O'Toole) 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. (official distributor synopsis)
