The New Gods film will take place before Justice League 2. Orion, Highfather, Darkseid and Mister Miracle will be the main characters.
Robert Zemeckis and Mathew Vaughn, who was also offered the Man of Steel sequel, are the top candidates to direct The Flash. The studio wants the Reverse Flash as the main antagonist with the character returning for a Flashpoint film somewhere down the line.
The Nightwing movie is moving extremely fast. Chris McKay and Bill Dubuque have been working on the script. Nightwing will be a police officer in Blüdhaven and retired from being a vigilante at the beginning of the film. Blockbuster will be the main villain of the film.
The Batgirl movie will focus on Barbara's mindset after regaining use of her legs and dealing with the trauma she suffered at the hands of the Joker. A flashback scene with the Joker will be in the film. Penguin will be the main villain.
The Batman film is being rewritten. Deathstroke will still remain part of the film but Matt Reeves is adding more villains. The story will focus on how crime in Gotham has risen due to Batman being busy recruiting the Justice League and fighting the forces of Apokolips . Batman has to return to Gotham to clean up the streets once again. The film will also set up Red Hood for the sequel.
The sequel to Man of Steel has been developing in secret. Geoff Johns and Zack Snyder finished writing a story for the film back in November. Multiple writers were approached to turn into a screenplay including the writers from Watchmen and the 300 movie series. Brainiac will be the villain and Supergirl will be introduced to the DCEU.
Wonder Woman 2 is pretty much a done deal. The main villain hasn't been decided but Cheetah and Circe have been discussed. The studio will most likely attempt to cast a big female lead to oppose Gal Gadot.
Early ideas that were discussed for Suicide Squad 2 included Maxwell Lord, Scarecrow or Bane as villains. Killer Frost will be added to the team and Diablo will return.
