Zachary Levi and Mandy Moore Join The Cast of Disney's Rapunzel Mandy Moore is Rapunzel – though she’ll be relieved that she won’t have to grow her hair. The 25 year-old singer/actress will lend her voice to Disney’s 3D retelling of the classic Brothers Grimm fairy tale, about a princess who is imprisoned in a tall tower, and escapes after she grows her golden hair to extraordinary lengths. Disney’s animated tale will pick up Rapunzel ’s story after she escapes from the tower, as she goes on the run from her evil captor, accompanied by a roguish bandit (voiced by Chuck star, Zachary Levi ). We’re just guessing here, but we imagine that the two will fall in love somewhere along the way. Rapunzel is something of a pet project for Disney chief, John Lasseter. Disney had been working on a new film called Rapunzel Unleashed for a while, but had yielded no results. So, when Lasseter came on board in 2006, he started from scratch, and Rapunzel is the result.
