Fan Casting Batman Unchained (1999)

Sometime after the events of Batman & Robin, 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.
