This Batman story is Inspired by the Batman comics The Man Who Laughs, the Killing Joke and some elements of "The Feat of Clay" episode from batman the Animated series and The Dark Knight.
Here is my fancast
Jeremy Edwards (Holby City, Hollyoaks) as Batman/ Bruce Wayne
Larry Lamb (EastEnders, Gavin and Stacey) as Alfred Pennyworth
Danny John Jules (Red Dwarf) as Lucius Fox
Philip Glenister (Life On Mars) as James Gordon
Danny John Jules (Red Dwarf) as Lucius Fox
Danny Webb as Roland Dagget
Julian Bleach as The Joker/ Jack Napier- My take on the Joker is that he was once an engineer who was fired from his company by his bosses. He was worried that he could not feed his family, so he was then payed for by some criminals working for Roland Dagget who in return wanted Jack Napier to commit some crimes under the guise as Red Hood, when Jack Napier did not want to do do any more, the criminals kidnapped his wife and held her in the Axis Chemical plant. he tried to save her but the criminals caught him and murdered his wife. As he attempted to beat up the criminals, they restrained him and dropped him in a tank of chemicals. when he ended up in the river he found out that his skin was bleached and from then on, the Joker was born. The reason why I picked Julian Bleach as the Joker, because of his role as the jokeresque Nightmare Man in the Doctor Who spinoff Sarah Jane Adventures. I think Julian Bleach would make a far better Joker than Heath Ledger
James Nesbitt (Cold Feet) as Harvey Dent/ Two Face
Archie Panjabi (Bend It Like Beckham) as Renee Montoya
Eva Birthisle (Waking The Dead) as Sarah Essen
Steve Pemberton (League Of Gentlemen) as Harvey Bullock
Peter Capaldi (The Thick Of It) as Sal Maroni
