Although the state of the Justice League is up in the air right now as far as Ben Affleck's involvement as Batman and who will take over for Henry Cavill as Superman, there are plenty of other promising projects coming out of the DC Extended Universe.
In just a few weeks, Jason Momoa will make a splash in Aquaman, and 2019 and 2020 will be full of highly-anticipated films as well. Outside of the DCEU, Todd Phillips's as-yet-untitled Joker film will see Joaquin Phoenix take a different approach to the Clown Prince of Crime.
Here's the current full schedule:
Aquaman: December 21, 2018
Shazam!: April 5, 2019
Joker: October 4, 2019
Birds of Prey: February 7, 2020
Wonder Woman 1984: June 5, 2020
As of right now, Aquaman and Shazam! are the only films to have trailers released, but plenty of photos and footage have been revealed from the set of Joker, as well as promotional photos from Wonder Woman 1984. Margot Robbie also recently revealed the full (and rather long) name of her upcoming film: Birds of Prey (and the Fantabulous Emancipation of One Harley Quinn). More and more info is coming out about these films by the day.
Other DC projects in the works include The Flash standalone film, Matt Reeves's The Batman, Suicide Squad 2, which will be written and possibly directed by James Gunn, and the as-yet-untitled Batgirl film, among others.
