Bolt started life as a script by American film animator Chris Sanders, who was also slated to direct. It was originally titled American Dog but was renamed/re-scripted when Chris Williams and Byron Howard took over directorship.
Bolt is an American White Shepherd who, because he plays a superdog on camera, thinks his superpowers are real. Bolt is voiced by actor John Travolta.
No. Although executive-produced by Pixar's John Lasseter, "Bolt" is entirely a creation of the Walt Disney Animation Studio.
