In addition to the recently announced Justice League: War - which is based upon Geoff Johns and Jim Lee's first New 52 story arc, Justice League: Origin - Warner Bros. plans to release two Dark Knight-themed movies in Son of Batman, an adaptation of Grant Morrison's 2006 comic book arc Batman & Son which reintroduced Damian Wayne into mainstream DC continuity, and Batman: Assault on Arkham, which is said to take place within the world of the Arkham video game franchise.
