The 3D version of Titanic opened in China last week on about 2400 movie theater screens in China. On its opening day (April 10), the 3D sinking ship saga brought in U.S. 11.6 million (RMB 73 million) making it the second highest opening day grossing film in China.
It does seem that this film is something of an event in China - a few of my Chinese students and friends (at least the female ones) have mentioned wanting to see it and its pretty rare for Chinese college students here to see films in theaters (they routinely watch them illegally for free online instead).
One slight bit of controversy involves censorship by the State Administration of Radio, Film & Television (SARFT) of nudity in one of the movies' scenes where Kate Winslet's breasts are exposed. Reportedly, the boob ban wasn't due so much to aversion of nudity, but to fear that Chinese theater goers would try to reach out to try and grab a feel of Kate's 3D bosom and thereby disrupt the view for other viewers. One disappointed viewer stated on a Chinese microblog site: "I've been almost waiting 15 years and not for the 3D icebergs" according to China Daily.
