Zac Efron and Taylor Swift both lend their voices to characters in the new Dr. Seuss film The Lorax, which premiered at Universal CityWalk in LA Sunday.
The film, based on Suess' 1971 book, has a modern-day theme of environmentalism. The movie also features the voices of Betty White and Danny DeVito and hits theaters March 2 -- what would be the 108th birthday of Seuss, who died at 87 in 1991.
