It’s really fun trying to find the influences for the next film. Here’s a synopsis for Odd Man Out from the Criterion site (followed by my overboard speculation)..
With our past discussions here about Freeze pulling off robberies to pay for Nora’s treatment, along with the Richard Kuklinski connection (he started out as a thief) maybe you can replace Belfast with Gotham in that synopsis, replace Mason with Fries and use it as inspiration for a third act? Better yet, for the Arkham Origins fans who want to see a bounty on Batman’s head, the idea could be to replace Mason with Wayne as the GCPD or the entire rogues gallery are after the vigilante known as Batman. POV driven, taking place over the course of one night much like Odd Man Out?
