You already know that Star Wars: Episode III -- Revenge of the Sith isn't going to be a bright and cheery movie -- not with a title like that, or a plot that will reveal the disfiguring calamity that helps turn the merely pouty Anakin Skywalker (Hayden Christensen) into the evil Darth Vader. But director George Lucas says that the upcoming film, due in theaters next May, is so dark that it may receive a harsher rating from the MPAA ratings board than the previous five Star Wars movies. At an event last week in New York to promote the recent DVD release of his first film, the 1970 sci-fi tale THX 1138, Lucas said that Sith may earn a PG-13, rather than the more kid-friendly PG of the rest of the episodes. ''This is the darkest of them all,'' he said, according to USA Today. ''I don't think it's going to be rated like the other ones. It's just more emotionally intense.''
Lucas also reiterated his denial, despite recent rumors, that he planned to shoot Episodes VII, VIII, and IX. Of Sith's wrapping of principal photography last month, he said, ''The final shot of Star Wars has been shot, and never will the cameras roll again.'' He didn't rule out more Star Wars animation or books, but he said he'd never make another Star Wars feature film. ''I've been working on it over the last 30 years,'' said the 60-year-old director. ''When you do a trilogy, it's a 10-year run. That's a lot of your life.''
