PHILADELPHIA (CBS) – With the summer movie season winding down on August’s fourth weekend, the box office was characteristically weak, as holdover films dominated the marketplace.

The action thriller, The Expendables 2, last weekend’s leader, made it two weekends in a row on top, even though it took in less than $14 million.

Second place went to The Bourne Legacy, which earned an estimated $9 million.

Third was the animated attraction, ParaNorman, with a total of $8 million.

And fourth was the political comedy, The Campaign, with $7 million.

The weekend’s three new mainstream releases — all thrillers — finished well below the leaders: the suspense thriller, Premium Rush, took in $6 million, good for sixth. The action thriller, Hit and Run, placed eighth with $5 million. And the horror thriller, The Apparition, was twelfth with $3 million.

Overall, industry-wide totals were just slightly ahead of last year’s pace.
