Animated adventure with a strong environmental message, based on the children's book by Dr Seuss and featuring the voice talents of Zac Efron and Taylor Swift. 12-year-old Ted (voiced by Efron) has spent his childhood in Thneed-Ville, an entirely artificial city. When Audrey (Swift), the girl of his dreams, expresses her desire to see a real tree, Ted sets out to find it. Along the way he meets the reclusive Once-ler (Ed Helms), who tells the story of the Lorax (Danny DeVito), a grumpy yet charming creature, who fights to protect his world after a revolutionary industrial invention leads to the total destruction of the beautiful forests surrounding Ted's town.
