One of the most popular characters on Sesame Street gets his own movie in this family comedy. Playful Elmo (voice of Kevin Clash) loves his blue blanket and would never want to lose it. So when it gets spirited off to parts unknown in the midst of a tug-of-war with one of his friends, Elmo sets out to find it and ends up in the grumpy kingdom of Grouchland, where Huxley (Mandy Patinkin) and the Queen of Trash (Vanessa Williams) rule over a dark and ill-mannered domain. Along with Elmo, several other favorite Sesame Street characters appear, including Oscar the Grouch (Carroll Spinney), Ernie (Steve Whitmire), and Bert (Frank Oz).
