Writing the feature is David Berenbaum ( Elf, The Spiderwick Chronicles), who is also reportedly working on another animated project with George Lucas. Space Jam fans (looking at you, Navarro...) will recall that this isn't the first animated/live-action feature Warner has attempted with Looney Tunes characters. In the case of that movie, they scored a big hit, but then there's always Brendan Fraser's bomb, Looney Tunes: Back In Action, to serve as a cautionary tale. Let's hope the Frase-dawg isn't going to be a part of this.
Warner has a trilogy of 3D short films being shown before similarly branded films, the first of which aired before Cats & Dogs: The Revenge of Kitty Galore. The second will appear with Legend of the Guardians: The Owls of Ga’Hoole, and the third with Yogi Bear. Terrible, terrible synergy.
Oh, also, I just wanted to share this image of shirtless Chuck Norris that I found HERE while googling Bugs Bunny pictures.
