Batman Unchained

Batman Unchained or by its original title Batman Triumphant is a cancelled sequel to the 1997 film Batman & Robin, which was planned for a release in mid-1999. The script for the movie was written by Mark Protosevich. Joel Schumacher would return as director after directing both Batman Forever and Batman & Robin. Unfortunately, the film was cancelled after Batman & Robin received poorly at the box office.

Plot
Sometime after the events of Batman & Robin, Batman, Robin and Batgirl find out about a crazy scientist named Jonathan Crane or known as “The Scarecrow” and flashbacks from the first three Batman movies were to be shown in the cancelled movie. 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 at the box office (mentioned earlier).
 * 2) George Clooney admitted that he hated playing Batman and refused to reprise his role.
 * 3) Joel Schumacher didn't want to make Batman fans mad again after Batman & Robin.
 * 4) Warner Brothers decided to put all future live-action Batman movies on hold until further notice.
 * 5) Warner Brothers also decided to focus on making more episodes of the animated Batman series.

Result(s)
In 2005, Batman came back to the big screen with Batman Begins and the film had some elements that were to be shown in the cancelled sequel.

Elements from the cancelled sequel were also featured in the 2015 game Batman: Arkham Knight.

Trivia

 * Since George Clooney admitted that he hated playing Batman, Joel Schumacher handed the role of Bruce Wayne/Batman to Kurt Russell.
 * Rumor has it that Madonna was another possible casting choice for Harley Quinn.
 * In response to how campy and child-like Batman & Robin was, Joel Schumacher wanted to make the film darker like the first film and Returns. Schumacher also wanted the film’s storyline ignore the events of Batman & Robin after he disappointed many fans of the earlier Batman films.
 * The film was supposed to be released to celebrate Batman's 60th anniversary.
