The Dark Knight set records with the biggest opening weekend last week with $153.3 million last weekend.

The Dark Knight doesn't look to be slowing down with the biggest second opening weekend at $75.6 million beating out previous record holder, Shrek 2.  Already the 23 top grossing movie of all time, The Dark Knight has earned a record fast $314.2 million in just 10 days.  Previous record holder was Pirates of the Caribbean: Dead Man's Chest in 14 days.

How did other movies fare in the box office last weekend?

• Step Brothers - $30 million
• Mamma Mia! - $17.9 million
• X-Files: I Want to Believe - $10.2 million
• Journey to the Center of the Earth - $9.4 million

Does The Dark Knight have what it takes to beat out the current biggest domestic earner of all time, Titantic?  James Cameron should be nervous.
