The upcoming Batman solo movie "Batman", starring Ben Affleck, might be set inside Arkham Asylum, a fictional psychiatric hospital appearing in American comic books published by DC Comics.
According to Batman-On-Film, the solo film would see Batman being locked up in Arkham and battling his foes, reports aceshowbiz.com.
It's still unknown whether the solo movie is a straight-up adaptation of the "Arkham Asylum" video game or Grant Morrison's graphic novel "Arkham Asylum: A Serious House on Serious Earth".
The script is written by Affleck along with Geoff Johns, who is also the screenwriter of "Wonder Woman".
Though the storyline is still under wraps, the actor says that the movie would be an original story that borrows elements from the "Batman" comic book series. Sources said that there would probably be "a lot of Batman villains" being included in the film.
Affleck made his debut as Bruce Wayne and Batman in "Batman v Superman: Dawn of Justice".
His other appearance as the Caped Crusader can be seen in David Ayer's "Suicide Squad" which hits US theatres on August 5, and "Justice League" which will arrive in the US next year on November 17.
