Fan CastingJoel Schumacher Batman 5: Triumphant

Batman and Robin would end up parting ways due to disagreements. Batman would soon discover facts about a mentally unstable scientist named Jonathan Crane, also known as "The Scarecrow". Flashbacks from the first three Batman films were to be shown in a dream sequence. Batman would also have hallucinations after being exposed to Scarecrow's fear toxins, in which he would see the Joker, The Penguin, Catwoman, Two-Face and The Riddler re-unite to judge him on trial. Harley Quinn was intended to appear in the movie as a character, rewritten as a toymaker and daughter of the Joker determined to get revenge on Batman for the death of her father. Later, Scarecrow deduces that Bruce Wayne is Batman, then offers an alliance with Harley Quinn, and she accepts, and they 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. 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.
