PHILADELPHIA (CBS) – With Labor Day weekend marking the end of the summer movie season, traffic at the nation’s multiplexes was even slower than was traditionally expected.

First place, almost by default, went to the debuting Jewish-themed exorcism thriller, The Possession, which earned an estimated and modest $18 million in its debut.

The weekend’s other new mainstream release, Lawless, the Prohibition-era crime drama that opened on Wednesday, was the runner-up with $10 million.

Holdovers rounded out the top five.

The Expendables 2, the box office leader the last two weekends, took third with $9 million, while The Bourne Legacy and ParaNorman were fourth and fifth with $7 million and $6 million, respectively.

Overall, industry-wide totals were lower than those of the counterpart weekend last year, on what was the quietest box-office weekend in months.
