Fan Casting My Batman Cast

Imagine a Batman film but set in Arkham, Like 2009's Arkham Asylum Game. Batman has been trapped in Arkham Asylum where he slowly unravels a conspiracy linking a number of strange occurrences in and out of Arkham. On the outside of Arkham Alfred, James Gordon and Lucius Fox are all trying to get Batman out of Arkham while Nightwing, Red Hood, Robin and Batgirl go and fight crime in Batman's absence. The strange occurrences would all link back to Hugo Strange, a Psychiatrist working alongside Joker and Riddler to keep Batman trapped in Arkham.
