Ewan McGregor lends his voice to this heartwarming animated feature about Rodney Copperbottom, a young robot inventor who dreams of making the world a better place. But when the evil Ratchet (Greg Kinnear) takes over Big Weld Industries, Rodney's dreams -- like his friends, including motormouthed Fender (Robin Williams) -- are in danger of becoming obsolete. Halle Berry, Amanda Bynes, Mel Brooks and Stanley Tucci co-star.
