DCMU (DC Multimedia Universe)

The DCMU, or the DC Multimedia Universe, is a media franchise and series of superhero films and television series, distributed by Warner Bros. Pictures and based on characters that appear in American comic books by DC Comics. The shared universe, much like the original DC Universe in comic books and the television programs, was established by crossing over common plot elements, settings, cast, and characters. The films are written and directed by a variety of individuals and feature large, often ensemble casts, including: Richard Madden, Adam Gregory, Jake Gyllenhaal, Vincent D'Onofrio, Jamie Alexander and more. The first film in the DCMU was Son of Krypton (2021), followed by Batman: The Arkham Conspiracy (2021). The films take place a decade prior to official release, with the first film taking place in 2008.

Development
In 2018, Mark Waid was set to direct a live action reboot of the Superman Franchise, (previously Man of Steel (2013)), launching a new Cinematic Universe for DC to work in. Much of the Man of Steel cast had been recast completely, leaving only Harry Lennix reprising his role. Jason Momoa returns from the previous franchise, however as Lobo instead. The same year, Matt Reeves had been hired to direct a reboot of the Batman films, starting with The Arkham Conspiracy. Development is said to come to fruition in 2021, with Son of Krypton slated for a June 11th, 2021 release, and The Arkham Conspiracy due on October 29, 2021. During 2020, the DCMU released the entire first "slate" of films they had planned, which included the already announced Superman and Batman films, an untitled Wonder Woman film, "The Trinity", a film starring Superman, Batman and Wonder Woman, The Flash: Rogue War, "Green Lantern Corps", a series focused on the titular heroes, an untitled Aquaman film, and an untitled Justice League film.

Son of Krypton (2021)
Kal-El of Krypton fights against an android powered by his only weakness, delivering a fresh take on the Superman mythos in his second year. The film introduces the live action debut of Martian Manhunter, and Supergirl's first return to the silver screen since 1984. The film was released on June 11th, 2021 in IMAX, 3D and 2D, and was made available for streaming on HBO Max after a month.

Development for the film first began in 2018, after the box office failure of Joss Whedon's Justice League. Mark Waid was approached by the studio to pitch his vision for the film, hired almost immediately to direct WallyGoat7's script. In March 2019, Richard Madden was attached to portray the Man of Steel, later being replaced for newcomer Adam Gregory. Madden was instead given the role of Batman, replacing the frontrunner Michael Fassbender. Other cast members include Laura Fraser as Lois Lane, Dan Stevens as Metallo, Vincent D'Onofrio as Lex Luthor, Harry Lennix as the Martian Manhunter, Erin Moriarty as Supergirl/Kara Zor-El, Alec Baldwin as Johnathan Kent, and Gerard Butler as Jor-El. The film began a new cinematic universe for DC, the first of 8 announced films/series.

Batman: The Arkham Conspiracy
Early in their respective careers, Batman and Robin uncover a mystery that intertwines with the newly developed Arkham Asylum. They must solve the mystery while simultaneously dealing with a tech thief on the rise. After 24 years, Robin and Batgirl return to the big screen, along with the live action cinematic debut of Hugo Strange. The film will be released on October 29th, 2021 in IMAX, 3D and 2D, along with being available to HBO Max subscribers a month after release.

Development for the film began in late 2018, originally landing Michael Fassbender to portray the Dark Knight. After concerns from the studio that Fassbender was too old to play a young Bruce Wayne, he was replaced by Richard Madden (who had originally been penned to play Superman). Matt Reeves returned to direct and produce the film, given a second chance after his film The Batman fell through in mid development. Written by WallyGoat7, the film also features Nick Robinson as Robin/Dick Grayson, Sadie Sink as Batgirl/Barbara Gordon, Charles Dance as Alfred, JK Simmons as Commissioner Gordon, Bryan Cranston as Hugo Strange, and Zoe Kravitz as Catwoman/Selina Kyle.

The film is set only a couple of months after Son of Krypton, however only referencing the film in throwaway lines.

Wonder Woman: The Spear of Destiny
Dealing as an origin for Wonder Woman and an introduction for the Justice Society, Wonder Woman and Steve Trevor must sneak into a Nazi occupied territory controlled by Vandal Savage, in order to change the tide of the war.

American actress Jaime Alexander was hired for the role of Wonder Woman near the start of 2018, signing a multi-film contract, with potential for a couple cameos in series too. Soon after the announcement of Wonder Woman's casting, Bruce Greenwood was cast as Jay Garrick, Colin Firth as Alan Scott, Sylvester Stallone as Ted Grant, Clive Owen as the Spectre, Blake Lively as Dinah Drake, and Jason Bateman as Charles McNider, along with Chace Crawford as Steve Trevor. Little is known around the details of development, but Patty Jenkins has been heavily rumored to return to her directorial role. The film has also been rumored to release in early-mid 2022. The movie is said to take heavy inspiration from both Wonder Woman (2018) and early JSA comics. Kurt Russell is also rumored to appear as Zeus, yet no casting information has been made clear for the film's main antagonist, Vandal Savage.

The Trinity: Warworld
As Batman, Superman and Wonder Woman are transported to an alien planet ruled by the malevolent dictator Mongul. In their first team-up, the trio builds chemistry as they must work together to escape.

Richard Madden, Adam Gregory and Jamie Alexander are all signed on to reprise their roles for the film. Given the film's darker tone, director Zack Snyder has been the frontrunner to direct the film, but little is certain. Snubbed from the Batman title, Michael Fassbender has also been rumored to return as the alien warlord Mongul, along with Henry Cavill, Bruce Willis and Christopher Judge. When asked about the direction of the villain's age, WallyGoat7 replied, "We don't know anything yet. The story is in early development, you'll just have to wait and see."

The Flash: Rogue War
Having lost to the Flash alone before, Captain Cold, Heatwave and the Mirror Master recruit Captain Boomerang and newcomers Golden Glider and the Trickster to pull off one last heist in Central City. It's up to the Flash alone to try and stop the newly formed Rogue Gallery. Most of the Rogues make their live action cinematic debuts in this film, and so does Iris and Wally West.

Development on the story is said to take place as soon as The Arkham Conspiracy's script is finished. With director Edgar Wright attached, Luke Mitchell was hired to play the titular role of The Flash, aka Barry Allen. Other confirmed castings include Willa Holland as Iris West, Thomas Barbusca as Wally West, Bruce Greenwood as Jay Garrick, Andrew Lincoln as Captain Cold, Luke Goss as Heatwave, Jamie Bell as the Mirror Master, Teresa Palmer as the Golden Glider, Evan Peters as the Trickster, along with Jai Courtney returning to reprise his role from Suicide Squad (2016) as Captain Boomerang. Interestingly enough, development on this film has gone the farthest (aside from Son of Krypton and The Arkham Conspiracy), despite being slated to release as the fifth movie in the franchise. WallyGoat7 cited this fact with an "increased interest" in the adventures of Barry Allen.

Untitled Aquaman Film
In 2019, Aquaman was set to receive a live action reboot. While very little is known about the film, an "Atlantis" series is rumored to enter development in 2024.

Untitled Justice League Film
In 2019, a Justice League film was confirmed to end the first slate of films. In 2021, it was revealed the team would be formed through a sort of backdoor pilot, in the final few episodes of HBO Max's Green Lantern Corps. Adam Gregory, Richard Madden, Jamie Alexander, John David Washington and Luke Mitchell are all slated to reprise their roles for the film, with the antagonist being the Secret Society, a team made up of each respective heroes top villains. After the release of Son of Krypton, it was rumored the film would instead turn into a 4 to 6 part miniseries for HBO Max, allowing for a longer story to be told with increased runtime.

Green Lantern Corps (Season 1)
Before Son of Krypton had been released, a Green Lantern Corps series was greenlit for HBO's streaming service, HBO Max. The first season would deal with Hal Jordan's rookie year as a Green Lantern, already casting John David Washington to play the seasoned veteran John Stewart. Benedict Cumberbatch and Rami Malek are both rumored to portray Sinestro, and Chris Pine remains a frontrunner for the main character Hal Jordan. Adam Gregory, Richard Madden, Jamie Alexander, and Luke Mitchell are all slated to reprise their roles in the series, with a creation of the Justice League taking place during the last three episodes.

The season is said to be comprised of 6-9 episodes, each at an hour. Development for the first season begins after The Trinity: Warworld is completed, which will run simultaneously with the untitled Aquaman's development.

Green Lantern Corps (Season 2)
Greenlit not long after the series had been announced, the second season deals with the fallout from Season 1's Justice League buildup and Sinestro's fall from grace.

Community
Anybody is allowed to edit/work on movies (excluding Son of Krypton, The Arkham Conspiracy, and the Flash film). For context, I'm building this universe from practically the ground up, so these are heroes just starting their careers (1-5 years in), and if they have sidekicks they'd be very young/first generation at this point. (EX: Dick Grayson would be like 15 and the only Robin so far.) If you start on a movie just let me know, I might have either advice or specific continuity I'd like you to follow. So uh yea join up :)
