The Christopher Nolan film now has an overall gross of $441.5 million, which, if the estimate hold true when the Monday numbers are released, will surpass Shrek 2 ($441.2 million) for third place on the all-time domestic box office chart. Only Star Wars: Episode IV - A New Hope ($460.9 million) and Titanic ($600.7 million) have all-time higher domestic grosses.

Not much noise was made at the art-house this weekend.

This week sees the wide releases Tropic Thunder on Wednesday and the new Alexandre Aja horror film Mirrors as well as the new animated Star Wars tale, Star Wars: The Clone Wars hitting theaters. Will either of these be able to take down The Dark Knight? We shall see in seven days.
