Many things about the DC Extended Universe are shrouded in uncertainty, both on and off the set.
Fresh rumours linking Ben Affleck with the Batcave exit seem to emerge every week, and the long-term future of the shared cinematic world itself is now in doubt after Warner Bros announced plans to pursue standalone superhero films.
As much as the fans would like to know what the hell is going on behind the scenes, there are plenty of unsolved mysteries still at large in the DCEU movies themselves, and these are more fun to explore, debate and wax lyrical about.
