Based on Dr Seuss's much-loved 1971 children's book, the film sees the former High School Musical star playing a character who seeks out the eponymous creature, as he attempts to stop the deforestation of his home.
Danny DeVito voices the Lorax, with Taylor Swift, Betty White and The Hangover's Ed Helms in the supporting cast.
