The way I imagined The Superman/Batman movie. Lex Luther (Bryan Cranston) reaches across the bay to Gothem’s richest citizen Bruce Wayne (now cast as Ben Affleck, though I didn’t have a casting choice in yet and I’m fine now with Affleck) in a voice of concern about this new caped crusader that nearly destroyed Metropolis in his battle with Zod (I didn’t mind the end of Man of Steel, Superman 2 had the same result, and in that one they laughed it off rather than Superman being upset about it). Batman comes over, they have a fight but they realize they are on the same time. Meanwhile Joker (no casting choices yet, I though about seeing if Mark Hamill would unretire his Joker, but this isn’t voice acting and Mark’s acting itself is what the question would be) along with my beloved Harley Quinn (also my beloved Katee Sackhoff ever since she started campaigning for it, though I might hold her off for a part in Justice League) starts causing havoc across both cities. Batman and Superman, not friends exactly, but working on the same side fight their common enemy, in the end finding that Luthor is the one pulling the strings and encouraged Joker, Luthor has something bigger planned… roll credits, tease Justice League (which is where Katee might be better cast as Wonder Woman, a tough roll to cast, Eliza Dushku would be possible, but doesn’t really fit the role as well physically, but perhaps that would be more the point).
