The news comes after Conroy posted an artist's rendering of him as an older Bruce Wayne on Twitter. "Paying attention you casting agents," he wrote in the post.

The event will also see Brandon Routh, who plays Ray Palmer/The Atom on DC's Legends of Tomorrow, play Kingdom Come Superman. The event will also feature Burt Ward, who played Robin in the '60s Batman television show, in an undisclosed role. It's unclear at this time just how major of a role Conroy will have in the production.
