Release Date: Spring 2010
Justice League: Crisis on Two Earths is a 2010 announced original direct-to-video animated film that is based on the abandoned direct to video feature, "Justice League: Worlds Collide" (originally titled "Justice League: Fearful Symmetry"), intended as a bridge between the then-concluding "Justice League" series, and its then about to be launched sequel series "Justice League Unlimited." The movie project was shelved because of insufficient staff to produce the movie and the TV show simultaneously. Crisis on Two Earths was reworked from the Worlds Collide script to remove references to the TV series’ continuity.
The premise of "Crisis on Two Earths" is borrowed from the 1999 Grant Morrison JLA: Earth 2 story, where a heroic Lex Luthor from an alternate universe coming to the Justice League for help against the Crime Syndicate but it is not an adaptation of that story. The film is the seventh in the line of the DC Universe Original Animated Movies line released by Warner Premiere and Warner Bros. Animation. Written by Dwayne McDuffie of the Justice League (TV Series) fame, it is a modified script by McDuffie for a previously canceled Justice League Unlimited prequel. The film is not a DCAU production in any way, nor is it connected in any way to the previously released Justice League animated film; Justice League: The New Frontier.
Muchos superpoderes, pero a la larga y como siempre Batman va a terminar salvándolos a todos.
