Michael Keaton did not reprise his role as Batman in "Batman Forever" due to creative differences and dissatisfaction with the direction of the franchise. After Tim Burton, who directed the first two Batman films, was replaced by Joel Schumacher, the tone of the series shifted towards a more colorful and campy style. Keaton felt that the new direction did not align with his vision for the character. Additionally, he was reportedly uncomfortable with the script changes and the overall approach to the film, leading him to decline the role.

"Batman Forever," released in 1995, was generally considered a commercial success, grossing over $336 million worldwide against a budget of around $100 million. While it received mixed reviews from critics, with some praising its visual style and performances (particularly Jim Carrey as the Riddler), others criticized it for straying too far from the darker tone of previous Batman films. Overall, it can be classified as a hit at the box office, though opinions on its quality vary.

Val Kilmer actually starred in "Batman Forever," released in 1995, portraying Bruce Wayne/Batman. However, he did not return for the sequel, "Batman & Robin" (1997), due to various factors, including creative differences and reported difficulties during production. The role eventually went to George Clooney. Kilmer's portrayal in "Batman Forever" was notable for its darker tone, aligning with the film's shift from the previous lighter interpretations of Batman.

Michael Keaton, who portrayed Batman in Tim Burton's films, expressed mixed feelings about "Batman Forever." He was originally approached to reprise his role but declined, feeling that the direction of the franchise was shifting. Keaton believed that the darker aspects of Batman were being sidelined in favor of a more commercial and colorful approach. He appreciated the character but felt that the tone of "Batman Forever" did not align with his vision of Batman, which was more nuanced and brooding compared to the film's lighter interpretation.
