The Batman -- Part II is one of the most anticipated films in DC's upcoming line-up and was being developed by Matt Reeves and Mattson Tomlin until the writer's strike put a pin on it. A spin-off series centered on The Penguin was in the middle of filming before the strikes shut down production on that project as well. Both will occur outside the new DCU and fall under the Elseworlds banner. Not many story details are out there about The Batman -- Part II yet, but some early reports claim Clayface will play a role in the sequel.
