We're really hoping Star Wars : Episode III is going to be good. George Lucas thinks:
"It's not like the old 'Star Wars,' " Lucas told theater owners at the ShoWest convention. "This one's a little bit more emotional. We like to describe it as 'Titanic' in space."
So this means either
1: George Lucas thinks the new Star Wars is like the movie "Titanic"
2: George Lucas thinks the new Star Wars should be compared to the ship that is commonly used as a metaphor of unparalleled disaster.
