Richard Donner's Superman launched the modern superhero film. It depicted Superman's life from Krypton to his first major challenge. The film starred many big names including Marlon Brando, Gene Hackman, Glenn Ford, and Ned Beatty. Unknown Christopher Reeve won the starring role and created a new Clark Kent. Every version of Superman since has been overshadowed by Reeve's performance. The wave of films Superman birthed ended with the Batman and Robin disaster in 1997. Bryan Singer's X-Men relaunched and reinvigorated the genre in 2000.
