Playing the lead in a TV show about a superheroic dog has gone to Bolt's (voiced by John Travolta) furry little head, giving the snowy-white pup the delusion he has real powers. Accidentally displaced from his Hollywood set, Bolt learns how dangerous the real world can be as he gets help from frisky feline Mittens (Susie Essman) and playball-bound hamster Rhino (Mark Walton) to find his way home. Disney's clever animated romp co-stars the voices of Miley Cyrus, Malcolm McDowell. 96 min. Widescreen; Soundtracks: English DTS HD 5.1 Master Audio, Spanish Dolby Digital 5.1; Subtitles: English (SDH), Spanish; bonus short "Super Rhino"; deleted scenes; featurettes; game. Two-disc set.
