This film has staying power, destined to endure for ages. It's truly an exceptional work of art. The creative team clearly had a firm grasp on their vision. Christopher Reeve delivers a remarkable performance; he’s incredibly impressive. He managed to distinguish Clark Kent and Superman as separate individuals while still maintaining the connection between them. Margot Kidder shines in her role as Lois Lane. Gene Hackman and Valerie Perrine are also excellent, embodying Lex Luthor and Eve Teschmacher respectively. Every member of the cast was superb. This film consistently earns a perfect score.
