Ultimately, Warner Bros. passed and Paul Dini moved on to write the animated feature Batman Beyond: Return of the Joker.
For those who may not be familiar, Batman Beyond takes place in Gotham City years in the future and sees Bruce Wayne aging out of fighting crime.
Having Clint Eastwood as an older, grizzled Bruce Wayne mentoring the young Terry McGinnis to become Gotham’s new Caped Crusader certainly would have been different.
For about as long as Batman Beyond has been around, fans have wanted to see the futuristic world of Gotham brought to life in live-action.
