An 8-bit video-game character attempts to shed his bad-guy image by escaping into a popular first-person shooter, but inadvertently wreaks havoc in the video-game universe by freeing a digital villain who can only be contained with the help of a most unlikely ally in this colorful animated adventure. Wreck-It Ralph (voice of John C. Reilly
) is the arch nemesis of Fix-It Felix (voice of Jack McBrayer
), one of the most beloved video-game icons of all time. In a noble bid to prove he is more than the sum of his programming, Ralph sneaks from his cozy retro home into a highly advanced combat game featuring battle-hardened soldier Sergeant Calhoun (voice of Jane Lynch
), and strives to prove his bravery by winning a medal. In the process, however, Ralph accidentally frees the greatest threat the video-game world has ever seen. But all hope is not lost, because if Ralph can just convince unpredictable cart racer Vanellope von Schweetz (voice of Sarah Silverman
) to help set things right, perhaps he can finally unleash his inner hero and save the arcade from certain destruction.
