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, Ian McKellen 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.

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 :)
