Batman Unchained

Batman Unchained is the name of a cancelled sequel to the 1997 film Batman & Robin which was planned for a release in mid-1999. The script for the film was written by Mark Protosevich, and was never known to have any other title. Joel Schumacher would return as director. Unfortunately, the film was cancelled after Schumacher and the studio agreed the hallucination finale would be far too costly, although he liked the story. Schumacher also decided to stop production on the film since Batman & Robin failed to outgross the preceding Batman films (Batman, Batman Returns and Batman Forever) and in response to the backlash the film received when it was theatrically released. The cancellation led to a second sequel pitch entitled Batman: DarKnight.

Plot
Sometime after the events of Batman & Robin, Batman, Robin and Batgirl find out about a crazy 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 also intended to appear in the movie as a character, namely a toymaker and daughter of the Joker determined to get revenge on Batman for the death of her father.

Why It Was Cancelled

 * 1) Batman & Robin failed to outgross its predecessors (previously mentioned).
 * 2) George Clooney admitted that he hated playing Batman and refused to reprise his role as Bruce Wayne/Batman.
 * 3) Despite interest in making the film, Joel Schumacher didn't want to make Batman fans mad again following the backlash of Batman & Robin.
 * 4) The entire story hinging on the hallucination in the finale would have been too costly due to all the starpower (mentioned earlier).
 * 5) Warner Brothers decided to put all future live-action Batman films on hold until further notice and focus on making more animated direct-to-video and DVD Batman films as well as the 2001 series Justice League, which featured Batman as one of the major characters in the series.
 * 6) The final draft of the script wasn't complete.
