Director Joel Schumacher is revealing that he really wanted to make an Arkham Asylum movie after Batman Forever.
In a retrospective interview in conjunction with the 20th anniversary of Batman & Robin (which was released on June 20, 1997), Schumacher shared in an interview with THR the hopes he had of doing an Arkham Asylum movie, which he effectively set up at the conclusion of Batman Forever.
Schumacher feels so bad for the misfire, in fact, that he recently apologized for it.
And it was just a nod to back to Arkham Asylum which I love, and I thought it would be fun to put the other villains up there.”
