In addition to The Suicide Squad and Wonder Woman 1984, we have Shazam!, a standalone film which, as far as we know, only makes passing references to the fact that other DC heroes exist, Birds of Prey, a film that will include one popular character that we’ve seen before, but will also introduce several new ones, a Batman movie that won’t include Ben Affleck, and thus could very easily not be part of the existing universe at all, a Joker movie that we know for certain is not connected to the version of the character played by Jared Leto in Suicide Squad, and a sequel to Aquaman, a movie that itself made only a brief reference to the fact that it starred the same character who was in Justice League.
This is also clear in the rest of the DC slate that we know is on the way.
One wonders if an Aquaman producer will come out of the woodwork to tell us Aquaman 2 is not a sequel.
