Batman Beyond is a straight-up killer idea. You take the best bits of the Dark Knight, combine them with a dab of Spider-Man, set it in the future and voila: awesomeness. But despite this, there's been little movement on the franchise since the animated series ended in the early 2000s. Since then, the Batman Beyond concept has been revisited in comic books, but there've long been rumblings of a live-action adaptation of the franchise.
