15 Crisis on Infinite Earths fan theories so crazy, they might be true

Will Mark Hamill appear as The Joker?
Just as Kevin Conroy is the most prolific Batman voice actor, there’s a man who’s been voicing his greatest foe for just as long. Like Conroy, Mark Hamill also first gave his voice to an iconic Batman character in Batman: The Animated Series — The Joker. It would be a joy to see him bring the character to life in live-action alongside Conroy’s older Bruce Wayne.
While Hamill might have already appeared in the Arrowverse as James Jesse, the Trickster, there’s nothing to say he couldn’t bring the Joker to life as well. After all, Brandon Routh will be playing both the Atom and Superman in the Crisis on Infinite Earths crossover. Conroy himself has even implied he would be up for the idea of Hamill to be cast as his Joker. Responding to a fan on Twitter, he had this to say:
It might not be too much of a stretch for Hamill to go from playing the Trickster to the Joker, but it would certainly be something the fans would love to see. As much as this crossover is about the culmination of the Arrowverse so far, there’s also a great deal of fan service to be delivered. That’s already come to pass with some of the announcements, so why can’t it happen again?
