Fan CastingBatman vs. Two-Face

Batman and Robin meet Gotham District Attorney Harvey Dent at a top-secret demonstration hosted by Professor Hugo Strange. With his assistant Dr. Harleen Quinzel, Strange operates a machine called the "Evil Extractor" designed to siphon evil from criminals and store it in a vat. Batman scoffs, noting there is no easy path to righteousness, but the machine does work—too well, as the Joker and other volunteers laugh manically in an attempt to overload the machine. The containment vat explodes, drenching Dent with liquified evil, which scars half his face and changes his personality. Harvey, now re-christened Two-Face, embarks on a criminal career as seen in the opening credits, all of which his attempts are foiled by the Dynamic Duo. He is eventually whisked to a hospital where his face has been given reconstructive surgery. His sanity has apparently been restored as well, and he is allowed to resume crimefighting as the assistant to the Assistant District Attorney.
