Zac Efron, Danny Devito and THE HANGOVER star Ed Helms are teaming up to bring another DR. SEUSS character to life on the big screen.
The trio will join Betty White and comedian Rob Riggle in Illumination Entertainment's untitled, environmental-themed new project.
DeVito will play Seuss creation The Lorax, who fights to halt the destruction of the world's forests, while Efron will portray Ted, a young boy who sets out to find out why the world has become so ugly.
White will play Efron's grandmother and Helms will voice the tree-chopping Onceler.
