World's Finest with Michael Keaton and Christopher Reeve
Christopher Reeve's final appearance as Superman was the low budget disappointment Quest for Peace in 1987. When Batman came out in 1989 with Michael Keaton, it was huge. Keaton and Reeve did team up in 1994, but it was for the rom-com Speechless . I felt Batman Returns had too much going on so I removed the Penguin and combined his story of running for mayor and Max Schreck's character and gave them to Lex Luthor so that would bring Superman into the story.
