Hamill will be back as Luke Skywalker in Star Wars: Episode IX despite the tragic twist in Episode VIII, and we can always hope that he’ll return as the Joker or one of his many other DC Comics characters for DC Universe.
All things considered, Knightfall seems like a way for Mark Hamill to showcase his talents without either a lightsaber or animation.
For now, we can for sure count on him tackling a brand new character on a series that is brand new for him.
