Joo know what time it is?

In only its 18th day in release, Warner Bros.’ The Dark Knight reached the $400 million mark in domestic sales on Monday, grossing $6.3 million for a total of $400.1 million so far. This easily beat the 43 days it took Shrek 2 to jump the $400 million boundary.

The film has shown remarkable legs, setting records all along the way. Over the weekend, the Batman sequel declined just 43% to $42.7 million from 4,266 theaters to come in No. 1 at the domestic box-office for the third weekend in a row, and beating new entry The Mummy: Tomb of the Dragon Emperor, which opened to $40.5 million.

The Dark Knight seems to be on its way to beating Titanic as the #1 movie of all time. Only time will tell whether it gets there or not.
