Gwangong VS Alien (2011)

When a dangerous alien creature attacks Hong Kong and disrupts our harmonious society, the People's Liberation Army sends out its greatest weapon - A giant Lei Feng robot controlled by elite operators from Mainland China, Macau, and Hong Kong. But when even the best of Mainland Chinese technology fails us, there's always one man we can count on: Gwangong, the legendary hero who stands for loyalty, justice, and righteousness. This ambitious, larger-than-life sci-fi action satire shows that faith is the greatest weapon we have against even the greatest evil.
