An article in Business Day on Monday about box-office results for the summer film season referred incorrectly to ticket sales for the 2007 Labor Day weekend compared with the same weekend in 2006. Sales increased 12 percent in 2007; they did not decrease. Also, the article misattributed a quotation about labor strife in Hollywood. It was Gitesh Pandya, publisher of the Web site Box Office Guru — not Brandon Gray, publisher of another site, Box Office Mojo — who said, “You don’t want to celebrate too much at a time when you’re negotiating new contracts.” Link
