The Giant King (2012)

We were born to be friends.

A re-interpretation of Ramayana, the Thai animation film tells the story of a giant robot, Na Kiew, who's left wandering in a barren wasteland after a great war. Na Kiew meets Jao Phuek, a puny tin robot who's lost his memory and is now stuck with his new big friend. Together they set out across the desert populated by metal scavengers, to look for Ram, the creator of all robots.
