'The Help'

Aptly, moviegoers celebrated Labor Day weekend by watching a film about underappreciated household workers. For the third-straight weekend, period dramedy 'The Help' was the top movie at the box office, ending the summer season by fending off three more action-packed newcomers: 'The Debt,' 'Apollo 18' and 'Shark Night 3D.'

From Friday to Sunday, 'The Help' earned an estimated $14.2 million, a microscopic dip of just 2 percent from last weekend. That's almost unprecedented for a movie in its fourth week of release. Credit the fact that the movie added 65 more screens this weekend (for a total of 2,843), along with the weakness of the competition. Over the full holiday weekend, the film earned an estimated $19.0 million, for a four-week total of $123.4 million.
