Daimajin

The peasants of a Japanese mountain village pray daily that the vengeful god Daimajin remains locked in the gigantic statue that serves as his prison. Unfortunately their lord's chamberlain decides prayer time is perfect for staging his long planned coup. His first act as the village's new dictator for life is to, of course, forbid their religion. Their first act is to basically inform him "you gonna get stomped by the statue someday." This ticks him off and he orders said statue destroyed. He is unsuccessful, and eventually the statue wakes up and begins destroying everyone, including the good guys. Because apparently helping those in need without stomping a few of them too means he's going soft or something.
