Written by Stan Berkowitz, with Darwyn Cooke (author of the award winning six issue limited series serving as the basis for the movie) serving as story and visual consultant, the New Frontier is scheduled for release late January 2008.
It has one of the greatest casts for an animated film, let alone a comic related animated film, and for my own part, contains the voice of Green Lantern that should also portray the hero in a live action film; David Boreanaz.
Below is the trailer released by WB, check it out, and be prepared to be blown away!
