Disney's latest 3D animation Wreck-It Ralph is a light family drama and time machine for 20/30 something.

The titular character Ralph is the villain of the arcade video game Fix-It Felix Jr. He does the same thing for 30 years - destroying a building other characters in the game build.

He dreams of becoming a hero, so he escapes into various other games such as Hero's Duty, a light-gun shooter game where he helps the game's hero battle against alien invaders. He later enters Sugar Rush, a kart racing game set on tracks made of sweets.

Many characters of classic games in the 1980s and '90s, such as M. Bison in Street Fighter and Clyde from Pac-Man, star in the film as supporting roles and reminders for young audiences.

The most difficult thing for Disney's animators, according to producer Clark Spencer, is to create the landscape of Fix-It Felix Jr. They have to use the most advanced computer technology today to create a convincingly rough and simplistic world.

The film will premiere in China on Nov 6.
