Fan CastingBatman: Finale (1999)

Sometime after the events of Batman & Robin, Batman (Michael Keaton) and Robin (Chris O'Donnell) would end up parting ways due to disagreements for Batgirl staying in school, Robin is no longer fighting with him and Bruce is no longer Batman. Bruce would soon discover facts about his mentally unstable childhood friend named Jonathan Crane (Brad Dourif), also known as "The Scarecrow". the scientist who has his fear of a mythological creature since childhood called Man-Bat. Batman would also have hallucinations after being exposed to Scarecrow's fear toxins, in which he would see the Joker, The Penguin, Two-Face and The Riddler re-unite to judge him on trial. Later, Scarecrow deduces that Bruce Wayne is Batman, and he concoct a scheme to psychologically break Batman and have him thrown in Arkham Asylum. In the film's climax, Robin shows up and saves his partner from Scarecrow alongside Catwoman. Batman exposed Scarecrow with fear toxins and Scarecrow became haunted by the Man-Bat while in Arkham Asylum. The film was planned to end when Batman goes on vacation to Bali after defeating his enemies and demons, then enters a cave full of bats and they fly all around him, as proof that he had gotten over his fears.
