Final Star Wars movie not for kids, says Lucas

Film-maker George Lucas has warned parents the sixth and final Star Wars movie is not suitable for young children.

Iconic director Lucas has told fans new movie Revenge of the Sith will be the darkest and most violent in the series, as Anakin Skywalker makes his hugely anticipated transformation from a promising Jedi apprentice to become evil Darth Vader.

All five previous Star Wars films have been rated PG (Parental Guidance) in America, but Lucas expects the final piece of the Star Wars puzzle to be rated PG-13, which strongly cautions parents about the film's content.

Lucas tells American news show 60 Minutes, "I don't think I would take a five or six-year-old to this. The film is much more dark, more emotional. It's much more of a tragedy."
