In this 2008 computer-animated Disney film, an adorable dog named Bolt (voiced by John Travolta) has been trained to believe that he has superpowers, and that his young owner, Penny (Miley Cyrus), is in perpetual peril, thanks to the schemes of the dastardly Dr. Calico (Malcolm McDowell). However, the loving and protective Bolt and his human companion are really actors in a popular TV show, a production that goes to great lengths to make sure it's star pooch remains in the dark about his fictitious life. When Bolt is accidentally transported off his show's Hollywood lot, he must find his way back home and contend with his not-so-super reality, aided by a scrappy alley cat (Susie Essman) and a very enthusiastic hamster (Mark Walton).
