Batman (Batman, 1989)
We all know that Michael Keaton played the superhero in the movie of 1989. But not everyone knows that Mel Gibson had even more chances. But Mel was already a mature actor and had the right to choose, and he thought the movie wouldn’t be that popular. But it became a $400 million box office success.
The other candidates were Charlie Sheen, Pierce Brosnan, and Bill Murray.
