Justice League: Crisis on Two Earths is a 2010 American animated superhero film released on February 23, 2010. It is based on the abandoned direct-to-video feature Justice League: Worlds Collide, which was intended as a bridge between the then-concluding Justice League animated television series and its then forthcoming sequel series Justice League Unlimited. Crisis on Two Earths was reworked from the Worlds Collide script to remove references to the TV series' continuity. The film is directed by Lauren Montgomery and Sam Liu and written by Dwayne McDuffie.[1]

The premise of Crisis on Two Earths is borrowed from the 1964 Gardner Fox Justice League of America #29–30 story entitled "Crisis on Earth-Three!" and the 2000 Grant Morrison JLA: Earth 2 graphic novel, with a heroic Lex Luthor from an alternate universe coming to the Justice League's universe for help against the Crime Syndicate. The film is the seventh of the DC Universe Animated Original Movies released by Warner Premiere and Warner Bros. Animation. The two-disc special edition also includes an animated short featuring the Spectre.

On August 11, 2015, Warner Home Video re-released the film in a combo pack which includes a DVD and Blu-Ray copy, a digital copy, and the graphic novel on which it was based.

In an alternate universe, heroic versions of Lex Luthor and Joker (called the Jester) are stealing a device called the "Quantum Trigger" from the headquarters of the Crime Syndicate (villainous version of the Justice League). When an alarm is tripped, the Jester sacrifices himself to allow Luthor to escape and kills J'edd J'arkus and Angelique (evil versions of Martian Manhunter and Hawkgirl respectively) with a bomb. Luthor is nearly captured by the remaining Syndicate members (Ultraman, Superwoman, Power Ring, Johnny Quick and Owlman) but escapes to the Earth of the Justice League by activating a device that enables interdimensional travel.

There, Luthor is mistaken for the evil Luthor and ends up strip-searched. The Justice League is summoned and Superman's x-ray vision confirms Luthor's reversed organs indicate that he is from a parallel Earth and that their Luthor is still incarcerated at Stryker's Island. The Justice League take the alternate Luthor to the Watchtower, where they learn of the Syndicate threat. As the Justice League debates the matter, Luthor hides the Quantum Trigger on the satellite. With the exception of Batman, the rest of the Justice League (Superman, Wonder Woman, Green Lantern, Flash and Martian Manhunter) travel to Luthor's Earth.

Arriving at the parallel Justice League's base, the heroes attack Syndicate targets. After a successful series of raids in which they capture Ultraman, the League confront President Slade Wilson, who releases Ultraman and explains that acceding to the Syndicate's demands saves millions of lives. His daughter, Rose, however, regards him as a coward. Martian Manhunter inadvertently reads her mind and explains that as a military man her father holds life more dear than others. Martian Manhunter later foils an assassination attempt on Rose by Archer (an evil version of Green Arrow), and the pair fall in love.

Owlman has developed a weapon, the Quantum Eigenstate Device (Q.E.D.), which the Syndicate intend to use as the equalizer to the threat of a nuclear reprisal. When pressed by Superwoman, Owlman reveals that he secretly plans to overthrow Ultraman and take control of the Crime Syndicate. He also admits the weapon can destroy entire worlds. Believing there are many parallel Earths, and that each one develops from the choices that each person makes, Owlman becomes obsessed with the idea that nothing he does can possibly matter, as there will always be parallel worlds with alternate outcomes. As a result, he searches for Earth Prime, the first Earth from which all other universes originated, intending to use the Q.E.D. to destroy the multiverse. Superwoman is excited by the idea and agrees to help him. Owlman sends Superwoman with three of her lieutenants to the League's dimension, and on the Watchtower, they battle Batman, Aquaman, Black Canary, Black Lightning, Firestorm, and Red Tornado. Superwoman and one of her lieutenants escape with the Quantum Trigger but are followed by Batman.

After a fight that ended with him gaining a broken rib, Batman defeats Superwoman and summons the League. Johnny, hopeful to reinstate fear in the Syndicate, decides to come down to commit big crimes. Power Ring rejects this because J'onn had arrested Scarlet Archer. Rose decides to learn the location of the Syndicate base to allow the Justice League to confront them. The League arrives at the Crime Syndicate's moon-base with the captive Superwoman, and eventually battle the Syndicate. Owlman fights off Batman and takes the Q.E.D. bomb to Earth-Prime, finding it to be uninhabited and lifeless due to an unknown cataclysm. Luthor speculates that a speedster might be able to vibrate and match the Q.E.D.'s temporal vibration and open a portal. Johnny Quick agrees to do so, as Flash is not fast enough.

Batman pursues Owlman to Earth-Prime, where they engage in a brutal battle. Owlman espouses his nihilistic philosophy, claiming that Mankind destroyed Earth-Prime, and that destroying Man in every universe is the only possible real choice. As they fight, both of them notice how similar they are. Batman teleports Owlman and the Q.E.D. to another uninhabited Earth; seeing that the Q.E.D. is triggered, Owlman allows it to destroy the alternate Earth, killing himself in the process. Batman returns to the Syndicate's Earth, where Johnny Quick dies from the strain of acting as a vibratory conduit. Despite this, he shows no ill will toward Batman and appreciates his ruse. Martian Manhunter returns, accompanied by President Wilson and the Marines, and together they arrest Ultraman, Superwoman, and Power Ring.

Wilson thanks the heroes for helping save the world and tells them he had ordered the National Guard to support the local police forces and resume on arresting the Syndicate members. Although Rose asks Martian Manhunter to remain with her, the group return to their dimension. Batman and Superman later discuss a membership drive while Wonder Woman keeps Owlman's invisible jet.

Voice cast


In 2004, Bruce Timm revealed that a DCAU direct-to-video Justice League feature was in development to connect Justice League and Justice League Unlimited.[7] The film was titled as Justice League: Worlds Collide. One of the objectives of the film was to explain how Wonder Woman acquired her Invisible-Jet. The project was ultimately scrapped by Warner Bros.; however, in 2008, Timm stated that Justice League: Worlds Collide could be released someday in the future.[1]

Finally, Worlds Collide was rewritten by Dwayne McDuffie for DC Universe Animated Original Movies as Justice League: Crisis on Two Earths, but removing all connections with the animated series.

Justice League: Crisis on Two Earths received positive reviews.[8] The World's Finest stated "...the film ranks up there as one of Dwayne McDuffie's better works in the animated DC world and even though it’s reminiscent of stories we’ve seen in animation before, the brilliant work done by Moi, the directing by Sam Liu and Lauren Montgomery, and story make it more than worth watching again."[6]

It earned $9.2 million from domestic home video sales.[9]
