China's censors have rejected worldwide box office champ "Pirates of the Caribbean: Dead Man's Chest" due to violent and supernatural content, reports Reuters and Hollywood Reporter.   The Walt Disney Pictures sequel could still screen in China if it passes a second round of examination, a source close to the film review process told the daily Beijing News Friday.   According to the paper, the Film Bureau disliked the portrayal of the souls of the dead and of a ferocious "octopus-faced" character. The bureau's representatives declined to comment. The Film Bureau typically rejects sex and violence but does not reveal the criteria. It passes only 20 foreign films each year for revenue-sharing theatrical release.   The first film in the "Pirates" franchise, "Pirates of the Caribbean: The Curse of the Black Pearl," screened in China in November 2003 and earned about $3.4 million.
