From Coming Soon:

While we await the four-day holiday weekend estimates on Monday, Warner Bros. Pictures revealed that The Dark Knight became only the second movie in Hollywood history to surpass the $500 million mark at the domestic box office on Sunday, bringing its total to $502.4 million. Titanic, the biggest blockbuster, remains in first on the domestic chart with $600.8 million.

Dan Fellman, head of distribution at Warner Bros., said he expects The Dark Knight to finish at about $530 million, though it could reach $550 million if business persists as strongly as it has.

We’re kind of sad that there is no way that The Dark Knight is going to break free of James Cameron’s romantic stangle-hold on the top-grossing spot, but we’ll have to settle for knowing that The Dark Knight has at least done its part to change the way cinema works for the next few years.
