Since Ben Affleck and Geoff Johns will be working on the upcoming solo Batman film titled "The Batman" There going to need some stories to choose from so here I have a list of options that seems most suitable for the upcoming film .
This seems to be the most popular choice, everyone wants to see this made into a movie and with Geoff Johns and Ben Affleck working on it, the film could be turn into something special. For anyone who not familiar with the Red Hood story arc it basically a former dead robin come back from the dead to become his own persona named the Red Hood, basically a batman who kills. Now that robin is no other than Jason Todd the second robin killed by the Joker in the famous "Death of a Family" story arc during the 80's. Granted there has been speculation that in the DC Expanded Universe that the death of Jason has already occurred ultimately making Ben Affleck Batman retired. There even a Robin suit in the batcave and a letter was sent to Bruce Wayne saying "you let your family die", speculation on who sent it varies from a disgruntled employee, Lex Luthor himself to stir up the pot, Joker or none other than Todd himself. Now obliviously Todd is angry and wants revenge on Bruce for letting him die by the hands of the Joker ultimately giving him is Red Hood persona. We wont know for sure who sent the letter until the film comes out, but it already feels like a Red Hood story line is brewing.
2. Court of Owls
The Court of Owls is a secret society that has ruled Gotham for centuries. They are one of Gotham oldest families and use money and murder to swift political influence throughout history. They have these highly trained assassins named talons who can carry out there deeds. The leaders of the organization are humans who wear owl masks. They have been around since the 1600's and has controlled Gotham with an invisible hand for centuries. Now this could make for a badass story line for the upcoming solo film because little do people realize Bruce Wayne has a sort of unknown connection to them and he starts to investigate this secret society and they Court sends talons to try and stop him. This has Affleck written all over it let hope if the Red hood story doesn't come into fruition this will.
3. Arkham Asylum
Arkham Asylum is a critically acclaimed video game in 2009 that is considered the greatest superhero video game of all time. This could be a good plot for the upcoming Batman film since Asylum features a older Batman as well and he trapped in the asylum where all his rogue gallery is trying to kill him in one night, now doesn't that sound like an interesting movie. Any Asylum lovers out there there a good chance a live-action adaptation of it might become a reality not too far from now, so be on the lookout.
4. Batman: Hush
Batman: Hush is a great story arc and one Affleck might pull inspiration from. It features Thomas Elliot, Bruce Wayne former childhood friend who wants revenge on him because his father saved his mother life when Elliot tried to kill his parents to secure there fortune. The story features a lot of characters like Catwoman, Robin, Nightwing, Superman and etc and could be a epic drama told on film something Affleck is very successful directing with.
So there you have it these are the stories i think could lead into inspiration for the upcoming solo Batman film in 2018 and ones that could best fit that story arc.
