"World Trade Center," Oliver Stone's movie about the rescue of two police officers from the towers on Sept. 11, will donate 10 percent of its opening weekend box office receipts to a ground zero memorial and three other Sept. 11-related charities.

The Paramount Pictures film, starring Nicolas Cage and Michael Pena as two Port Authority of New York and New Jersey police officers trapped for hours in the rubble, opens Aug. 9 at more than 2,000 theaters nationwide.

Five percent of the box office proceeds from Aug. 9 through Aug. 13 will be donated to the World Trade Center Memorial Foundation, which is raising money to build a $510 million memorial to the 2001 terrorist attacks at the trade center site.

An additional 5 percent will be split equally between three charities: Tuesday's Children, a services organization for children who lost a parent on Sept. 11; The Tribute WTC Visitor Center, a family run memorial museum scheduled to open this summer; and the New York Police and Fire Widows' and Children's Benefit Fund.
