Not much to it. But Comic Book Resources has a two-minute clip from the movie! I stole if for ya:
"Superman/Batman: Public Enemies" features a star-studded voice cast filling the roles of super heroes and villains alike, including Kevin Conroy (Batman), Tim Daly (Superman), Clancy Brown (Lex Luthor), Allison Mack (Power Girl), Xander Berkeley (Captain Atom), Ricardo Chavira (Major Force), John C. McGinley (Metallo), LeVar Burton (Black Lightning), CCH Pounder (Amanda Waller) and a host of others.Superman looks pretty violent in that, eh?
Here's a funny: The embed code for the trailer comes from the official movie site, but it's sourced out from MySpace. Warner Bros. is also doing some sort of (I didn't read the details) contest. When you click on that link: it takes you to Facebook. Wonder if the right hand knows what the left hand it doing? Heh.
