“Batman buried his rivals at the North American box office for a second weekend on Sunday, racing past $300 million in a record 10 days.

The Caped Crusader’s blockbuster outing, “The Dark Knight,” sold an estimated $75.6 million worth of tickets during the three days beginning Friday, taking its total to $314.2 million, distributor Warner Bros. Pictures said.

A week after it scored a record-breaking $158 million opening, “The Dark Knight” added a new title to its impressive list of superlatives: the best second weekend, surpassing the holiday-boosted $72 million haul of 2004’s “Shrek 2.”

The $180 million movie, which stars Christian Bale as Batman and late actor Heath Ledger as the anarchic Joker, has reportedly been drawing strong repeat business, and also has piqued the interest of people who avoid superhero flicks or rarely go to the movies at all.

“The Dark Knight” now ranks as the second-biggest movie of the year, just behind the $315 million haul of “Iron Man,” and the 23rd-biggest of all time.” [...]
