For the fourth week in a row, The Dark Knight has managed to hold on to its place at the top of the domestic U.S. box office. With the arrival of two more movies to make a play for the top spot, Pineapple Express and The Sisterhood of the Traveling Pants 2, some of us thought it might take a fall to number 2. But it has held strong, and taken the second largest grossing film of all time within just 24 days.

TDK managed a reasonable $26 million, beating out Pineapple Express which itself managed a respectable $22.4 million. Sisterhood came out with a $10.7 million haul, not too bad considering not only the geeky competition, but the chick-movie subject matter of a movie starring four girlfriends.

But as mentioned, TDK in only 24 days has managed to take the second largest grossing film of all time, with a total of $441.5 million, compared to Titanic‘s $600.7 million. TDK ‘s place at number one however is definitely tenuous, with Star Wars: The Clone Wars being released this weekend; a heady challenge for any period in a movie’s run.

But TDK is still going strong to beat Titanic’s overall gross. At only 24 days, TDK has a long way to go before it reaches the nine months that Titanic ran at U.S. theaters.

As always, thanks to Box Office Mojo for statistics.
