Sci-fi spin-off Ratchet & Clank's unlikely galactic heroes get a boost from a surprisingly starry voice cast featuring Sylvester Stallone, Rosario Dawson and John Goodman.

Ratchet & Clank

A bright-eyed bushy-tailed space feline and a titchy big-brained robot become evil-foiling allies in Ratchet & Clank, a breezy cartoon sci-fi adventure based on the popular PlayStation games.

Ratchet (voiced by James Arnold Taylor) is a sparky young mechanic with dreams of joining the Galactic Rangers, the team of heroes tasked with defending the Solana Galaxy, while Clank (David Kaye) is a defective robot who has slipped free from the production line of mechanical soldiers being assembled by megalomaniac villain Chairman Drek (Paul Giamatti) and mad scientist Dr Nefarious (Armin Shimerman).

The ensuing adventure lacks the storytelling smarts of Pixar and the computer animation isn’t exactly cutting edge, but the action is lively and colourful enough to keep young kids engaged. Older viewers, meanwhile, can occupy themselves trying to spot the voices of Sylvester Stallone, Rosario Dawson and John Goodman among the surprisingly starry supporting cast.
