that's true my bad.
here's an article from cnn.com in todays news
Christensen, who joined the cast as Anakin in "Episode II," figures the final installment will end so darkly the film might have trouble getting a PG rating like its five predecessors (though shrewd businessman Lucas likely will design the film to avoid a PG-13 so pre-teens can see it without an adult chaperone).
Obi-Wan Kenobi and Anakin Skywalker have a split in "Episode III."
"I think he will end almost on an apocalyptic note," Christensen said. "I just can't imagine it not being an incredibly dark and destructive film."
"You've got a war, and what we know from the previous trilogy, what my character does in wiping out the entire Jedi race, and the falling apart of my relationship with Obi-Wan."
"Episode III" will take place a few years after the action of "Attack of the Clones," Lucas said. After that, there is a 20-year gap before the events of the first "Star Wars," when young farm boy Luke meets Obi-Wan, Leia and Han Solo and is hurled into the rebellion against the Empire.
After it became a box-office phenomenon, the 1977 original was retitled "Star Wars: Episode IV -- A New Hope" to set up the two sequels and eventual three-part prequel.
In keeping with that title, Lucas said, there will be some sense of hope as the dark curtain falls on "Episode III."
The director said he already filmed one of the last images of "Episode III" during production of "Attack of the Clones."
"It's not the exact closing image, but it's one of the final images," Lucas said. Laughing, he added: "I won't say what it is."
