Justice League: Crisis on Two Earths (film)

Justice League: Crisis on Two Earths is an imagined film in the DC Cinematic Universe and the seventh film in the Justice League film series. It kickstarts the final trilogy that will end the DCCU. It is based on the "Crisis on Earth-Three" storyline and serves as a precursor to "Crisis on Infinite Earths". It takes place after the events of Justice League Dark and Flashpoint. It is the first Justice League film to not feature Superman and Wonder Woman.

It stars Lucas Hedges, Bryan Cranston, Samara Weaving, Jason Isaacs, Morena Baccarin, Corey Fogelmanis, and Lily James.

Plot

 * It was revealed in Flashpoint that a being of unspeakable power is causing destruction in the "multiverse" and that Barry Allen's disruption of the timeline allowed Earth-1 to stay hidden from the destruction.
 * After the events of Justice League Dark, the league began an aggressive recruiting program, to make up for the death of Superman, departure of Wonder Woman, and depowering of Shazam!. New members such as Black Canary, Big Barda, Vibe, Animal Man, Steel, Spartan, Black Lightning, and Hawkgirl were taken in.
 * Lex Luthor of Earth-2 escaped the Syndicate (evil version of the Justice League) and stole the Quantum Trigger, using it to arrive at Earth-Prime. He meets Cyborg (this was the credits scene in Flashpoint).
 * The Syndicate of Earth-2 developed the Quantum Trigger after learning that the being known as the Anti-Monitor is destroying other universes, and will eventually destroy Earth-2. The Anti-Monitor has its origins traced to Earth-Prime and the Syndicate believes that destroying Earth-Prime would destroy the Anti-Monitor. Lex Luthor was not convinced of this and believes it is unethical, so he stole the Quantum Trigger and went to Earth-1 to warn the Justice League.
 * Luthor convinces the Justice League to join him to Earth-2 to destroy the Syndicate. An argument ensues between league members. Half of the team is skeptical about helping other "Earths" as this would open a Pandora's box. Supergirl, The Flash, Black Canary, Blue Beetle, and Donna Troy are in favor of helping while Batman, Cyborg, Aqualad, Vixen, Doctor Fate, Big Barda, and The Atom advise against it. Hawkgirl is a new member after arriving at the end of Hawkgirl: Mysteries in Space. Doctor Fate is unable to see parallel realities. An argument ensues, however, and Supergirl, The Flash, Blue Beetle, Black Canary, Donna Troy and Lex go to Earth-2.
 * The Justice League arrives on Earth-2 and are secretly greeted by its advanced military to take down the Syndicate. Luthor is joined by the remaining heroes of Justice Underground, Jokester and Thaal Sinestro.
 * The allied forces attack the main members of the Syndicate at their headquarters: Ultraman (anti-Superman), Ultragirl (anti-Supergirl), Superwoman (anti-Wonder Woman), Owlman (anti-Batman), Power Ring (anti-Green Lantern), Johnny Quick (anti-The Flash), Black Beetle (anti-Blue Beetle), and White Claw (anti-Black Canary).
 * Ultraman taunts the Justice League for the death of Superman (which occurred in Justice League Doom). The combined forces of the Justice League, Justice Underground, and the militia are able to take down the members of the Syndicate, and they are arrested in front of the world. Blue Beetle, however, is killed in the battle.
 * The Justice League returns to Earth-1 and the members who stayed get upset that Blue Beetle lost his life over helping another Earth.
 * A public campaign starts to form on Earth-2 to release the Syndicate. The public expresses sympathy for them getting arrested and beaten in front of everyone. Also, Owlman is able to release information that they were trying to save the world. Syndicate members Grid (anti-Cyborg) and Sea King (anti-Aquaman) are able to release Ultraman, Superwoman, Owlman, Power Ring, and Johnny Quick from prison.
 * Shortly after, it is revealed that Owlman, a nihilist, wants to destroy Earth-Prime because it would destroy all earths. He and Superwoman overthrow Ultraman as leader of the Syndicate and start planning the destruction of Earth-Prime. Superwoman, Johnny Quick, Atomica (anti-The Atom), Sky Tyrant (anti-Hawkgirl), Grid, and Sea King travel to Earth-1 to retrieve the Quantum Trigger.
 * A surprise attack on the Justice League headquarters allows the Syndicate to overpower Supergirl, Donna Troy, and The Flash. Batman, however, has been studying Earth-2 with Mister Terrific and decides that the Syndicte is a threat to all of the multiverse. He then appears with other league members Cyborg, Hawkgirl, Vixen, Aqualad, Big Barda, Black Lightning, The Atom, Black Canary, Maxima, Plastic Man, Black Canary, Steel, and Spartan.
 * Johnny Quick opens a portal to send the Quantum Trigger to Owlman, but is killed in the process.
 * Power Ring and Owlman go to Earth-Prime to set up the Quantum Trigger. Power Ring finds out the truth, but Owlman then kills Power Ring.
 * In the Justice League headquarters on Earth-1, the Justice League defeats the Syndicate. Sky Tyrant is killed. Sea King, Atomica, and Grid are able to escape back to Earth-2. Superwoman is imprisoned.
 * Batman is able to travel to Earth-Prime using the portal that Johnny Quick created, and has a brutal fight with Owlman on the barren Earth-Prime.
 * Batman is able to defeat Owlman and destroys the Quantum Trigger.
 * Batman, nearly dead due to the lack of oxygen on Earth-Prime, which has left the Sun's orbit many years ago due to an unknown cataclysmic event, is saved by The Spectre and Doctor Fate and is returned to Earth-1.
 * Lex returns to Earth-2.
 * Batman convenes a meeting with the Justice League (Supergirl, Hawkgirl, Aqualad, The Flash, Donna Troy, Cyborg, Big Barda, The Atom, Maxima, Plastic Man, Spartan, Steel, Doctor Fate, Vibe, Booster Gold, Black Canary, Mister Terrific, Black Lightning, and Animal Man) to end any riffs associated with the arguments earlier in the movie. He assumes leadership and The Spectre tells him that he senses infinite more crises to take place.
 * In the first credits scene, Cyborg deduces that the Syndicate was correct in that the Anti-Monitor is destroying universes and it is only a matter of time before it comes to Earth-1.
 * In the second credits scene, Psycho Pirate (last seen in Hawkgirl: Mysteries in Space) is approached by the Anti-Monitor in an unknown setting.
