The Dark Knight may have broken its last record this week. The highly successful movie has surpassed the $500 million mark in the US box office this weekend. Its total take domestically now stands at $502.4 million. Titanic, which still holds the top spot, has a domestic haul of $600.8 million.

TDK is only the second movie after Titanic to break the 500 million mark and now has the record for the fastest to reach that mark by doing it in 45 days, compared to Titanic, which reached it in 98 days. Another piece of interesting information is that Titanic reached the 600 million mark in 252 days. This means that if TDK could actually last that long, it has a big chance of beating Titanic.
