Batman: Arkham Asylum owes its existence to a failed game tie-in for Christopher Nolan's "The Dark Knight" movie developed by EA and Pandemic Studios. Because Pandemic was unable to finish the game in time for the release of the movie, EA $100 million in revenue and Pandemic was forced to close in 2009. With Eidos in control of the game license, they charged British game developer Rocksteady Studios with creating the next Batman game, which became Arkham Asylum.
