I'm not sure if I'd start with this, but I'd love to see a JSA movie set in the 1940s with a strong Darwin Cooke feel to it. We saw hints of how cool this would be with WW and starting things off this way would give the DCEU that sense of deep history that I think is missing in both current cinematic universes. WW would provide the continuity between this group and modern times. There would be no Superman in this JSA.
