This is a bit of old news, but for those who want to see a high res HD version of The Ant Bully teaser/trailer, you can check it out on Apple's Quicktime website. Apparently Warner Bros recently had a test screening of the work in progress film and it scored very high with the test audiences.
And for what it's worth I took my shot from the trailer (the rapping ants scene depicted above) and put it up in the Animation section of my site. That's right, Chubby White Boy animated hip hop rapping ants. I've got street cred now, yo.
