And the upcoming following DC Animated Movie will be an adaptation of Marv Wolfman and George Perez classic storyline Teen Titans: The Judas Contract! Only it's being updated and modernized since all curent DC Animated Movies have been set in the same universe/continuity.
Check out the trailer:
On one hand: classic DC tale finally getting the animated treatment! Deathstroke!
On the other: I would have love to see it retain the original George Perez art style. And it's weird seind Blue Beetle in there (to fill in for Cyborg, since he's part of the current JLA roster).
