A little 'Justice League: Crisis on Two Earths' background:
"Justice League: Crisis on Two Earths is an original story from
award-winning animation/comics writer Dwayne McDuffie (Justice League)
rooted in DC Comics’ popular canon of “Crisis” stories depicting
parallel worlds with uniquely similar super heroes and villains. Bruce
Timm (Superman Doomsday, Green Lantern) is executive producer. Lauren
Montgomery (Wonder Woman, Green Lantern) and Sam Liu (Superman/Batman:
Public Enemies) are co-directors."
The scene basically sets up the film's primary conflict with Lex
Luthor (voiced by Chris Noth) explaining the plight of his Earth, and
attempting to recruit the Justice League to join the battle against
the Crime Syndicate.
'Justice League: Crisis on Two Earths' will be available February 23, 2010 from Warner Premiere, DC Comics and Warner Bros. Animation.
This just keeps looking better and better all the time.
