Aquaman and the Lost Kingdom is finally out in theaters after several delays in getting to the big screen. Not only that, but it marks the final film in the DCEU as James Gunn and Peter Safran take over the reins from here on out. With so much riding on the possible final outing of Jason Momoa's Arthur Curry, you might be wondering just how it all signs off with the Aquaman and the Lost Kingdom post-credits scenes.
