Clifford's Really Big Movie (2004)

Synopsis
Clifford the Big Red Dog finally arrives on the big screen in the animated adventure Clifford's Really Big Movie, directed by Robert Ramirez. Clifford (voice of the late John Ritter) lives on Birdwell Island with his owner Emily Elizabeth Howard (voice of Grey DeLisle). Even though he loves the Howards, Clifford starts to think that his enormous size is too much of a problem for them. Feeling unwanted, he runs off and joins the circus with his friends Cleo (voice of Cree Summer) and T-Bone (voice of Kel Mitchell). They fall in with a gang of other runaway animals, including a Chihuahua and a ferret. The dogs compete in a big contest in order to win a lifetime supply of Tummy Yummies. Clifford's Really Big Movie encourages preschoolers to develop trust, independence, and confidence. ~ Andrea LeVasseur, All Movie Guide
