Titanic is bigger than Avatar when you adjust for inflation.
Anyways I think this kind of redeems the Star Wars franchise ... I said it even waaaaay back in 1999, at least domestically IMO Episode I should have beat Titanic, but it was simply too bad of a movie.
The prequels are fortunate they had the hook of "we gotta see Darth Vader" that kept people coming back.
Now we are seeing what Star Wars can do when it has the feel/tone/human element of the original trilogy. Box office records falling right and left.
