Bolt is a 2008 American computer-animated comedy film produced by Walt Disney Animation Studios, and is its 48th animated feature. It is the first film directed by Chris Williams (who previously worked on Mulan and The Emperor's New Groove) and Byron Howard (who previously worked on Lilo & Stitch and Brother Bear). The film stars the voices of John Travolta, Miley Cyrus, Malcolm McDowell, Claire Holt, Diedrich Bader, Nick Swardson, Greg Germann, Susie Essman and Mark Walton.
The film's plot centers on a small white dog named Bolt who, having spent his entire life on the set of a television series, thinks that he has super powers. When he believes that his human, Penny, has been kidnapped, he sets out on a cross-country journey to "rescue" her.
Bolt escapes from his on-set trailer mistakenly believing Penny has been kidnapped by the television villain. He attempts to break through a window, knocking himself unconscious as he falls into a box of styrofoam peanuts. With no one aware Bolt is in the box, it is shipped from Hollywood to New York City. In New York, he meets Mittens, a female alley cat who bullies pigeons out of their food. Bolt, convinced this is another adventure, forces Mittens to help him get back to Hollywood, and the two start their journey westward on a truck after Bolt knocks Mittens unconscious. Meanwhile, in Hollywood, Penny is deeply saddened over Bolt's disappearance but is forced by the studio to continue filming with a Bolt lookalike. As their adventure a proceeds, Bolt starts to notice that his superpowers aren't working, and rationalizes this is the effect that styrofoam has on his body.
Penny and her mother subsequently quit the show when their agent attempts to exploit the incident for publicity purposes. Penny herself adopts Mittens and Rhino, and moves to a rural home to enjoy a simpler, happy lifestyle with Bolt and her new pets. The show continues, but with a replacement "Bolt" and "Penny"- "Penny's" new appearance being explained in the show as being serious injuries necessitating her undergoing facial reconstruction surgery-, and adopting an alien abduction storyline (one that even Rhino finds unrealistic, and Bolt finds "ridiculous").
