From Slashdot (which is not for pornography [cough]):

An anonymous reader writes "The BBC is reporting that the Revenge of the Sith is a blood bath and is to recieve a PG-13. One notable point from the article is Lucas is quoted as saying "But I have to tell a story. I'm not making these, oddly enough, to be giant, successful blockbusters. I'm making them because I'm telling a story, and I have to tell the story I intended." As he lit a cigar with a large stack of burning 20's."
