A fan casting project born from a lifelong love of DC’s most iconic interpretations across animation, film, and television. This project embraces beloved canon casting from the expanding DCU under James Gunn, while hoping Matt Reeves’ The Batman continuity remains an Elseworlds project — allowing him to continue his acclaimed vision for Gotham and its villains, while leaving room to cast a Bat-Family from scratch within the DCU. Rooted in appreciation for The Dark Knight Trilogy, Justice League / Justice League Unlimited, DCAMU hits (under the Red Hood, Flashpoint Paradox, apokolips war, Teen Titans, Young jystice, The Penguin TV series and the list goes on. this project is not about reinventing DC — but honoring what works and building respectfully and thoughtfully around it and through the rest of the unfolding DCU roadmap.
