From MTV Splash:
“Written by Justice League alumni Dwayne McDuffie and Bruce Timm serving as executive producer, the feature borrows themes from DC’s “Crisis On Infinite Earths” and Grant Morrison’s “JLA: Earth 2” storylines with a heroic version of Lex Luthor traveling from a parallel Earth to enlist the aid of the Justice League in thwarting their evil counterparts, The Crime Syndicate. Owlman stands out as the most notable foe, apparently putting “the balance of all existence in peril” according to Warner Bros.”
The feature’s voice cast will include stars Mark Harmon (“NCIS”) as Superman, James Woods (“Ghosts of Mississippi”) as Owlman, Chris Noth (“Sex and the City, Law & Order”) as Lex Luthor, William Baldwin (“Dirty Sexy Money”) as Batman, Gina Torres (“Serenity,” “Firefly”) as Super Woman and Bruce Davison (“X-Men”) as the President.
A tentative release date for “Justice League: Crisis On Two Earths” is set in Spring 2010.
