i'm not too sure, but that looks like to me to be a false domestic take since it looks like it includes all the numerous re-releases as well as the 97 special edition. it should be adjusted to reflect only the 1977 gross adjusted.
Plus if we are talking about not readjusted gross titanic is still number 1 and no star wars film ever beat it. Sad but true and no movie has yet to break its record of #1.
Return of the King and Revenge of the Sith made valiant efforts, even rotk tied titanic for number of oscars.
I am kind of biased when it comes to Wall E since i loved artoo detoo in star wars and ben burtt worked on wall e, so i like the movie. I do hate the pc save the earth garbage but i'm not sure it was overly done, still i wonder if they had al snore as adviser on this film.
