A trailer for the upcoming 3-D computer animated version of Dr. Seuss' environmental tale, The Lorax, has arrived. Danny DeVito, Ed Helms, Betty White, Zac Efron, and others lend their vocal talents to the story about a boy who tries to fulfill the one wish that the girl of his dreams has: to see a real tree. In order to do so, he has to contend with the Lorax — a grumpy, but lovable creature that acts as a guardian against his world. The film marks the fourth Dr. Seuss fully computer animated feature

The animated adventure sees Danny DeVito as the titular character, while Ed Helms plays the part of the Once-ler. (In the book version, he's the greedy and mysterious being who is obsessed with the town's colorful Truffula Trees.) Zac Efron plays the boy Ted who tries to win the affections of Audrey — voiced by singer Taylor Swift. Betty White is Grammy Norma (cute!), and The Hangover's Rog Riggle takes on "financial king" O'Hare.

Check out the trailer for the film and a few still images below. You can see The Lorax in theaters on March 2, 2012.
