7) Arkham Asylum
Less of a high-security psychiatric unit and more of a quick pit stop before the inmates break out again, Arkham Asylum is a major element of the Batman mythos, and you can be sure that the building’s appearance here will be far from its last in the DCEU.
While most of the squad are held at Belle Reve Penitentiary, we get to see Arkham through flashbacks to Harley’s origin story. Rather than the toned down hospital from the Dark Knight films, the DCEU’s Arkham looks to be the gothic haunted house that fans know from the comics.
Rumours state that the upcoming Batman solo movie will heavily feature the Asylum, with roles for lots of the Bat’s rogues gallery. There’s been nothing official as yet, but this would make sense given the popularity of the Batman: Arkham games.
