With the excitement of the DCU's progression comes the prospect of casting its biggest heroes and villains, and Batman's extensive and iconic rogues gallery is among the most anticipated. So far, the confirmed DCU cast is mostly confined to 2025's Superman, which began filming in late February. As for the cast of the DCU's Batman movie, The Brave and the Bold, details are decidedly scarce, with the fact that it will star Batman, his son Damian Wayne as Robin, and other members of the Bat Family being among the only confirmed details.
