The German director’s [Roland Emmerich] “2012” movie was a hit in China with a plot that was gold for patriotic Chinese audiences: As the Earth’s core overheats, world leaders build an ark in the mountains of central China to house people and animals that can repopulate the planet. Scenes from the nearly three-hour movie feature a U.S. military officer saying that only the Chinese could build an ark of such a scale so quickly.
It was seen in China as a refreshing change for audiences after decades of unflattering portrayals of the communist nation in Hollywood movies.
Emmerich said he didn’t make “2012” specifically to appeal to Chinese.
There is more here. You will note that in Pacific Rim they do not kiss, respect and loyalty to family are major motives in the plot, and there is nothing approaching a nude scene, except when the female lead sneakingly admires the torso of the male lead.
