Football film "The Blind Side" tackled the top spot at North American box offices with $20.4 million in ticket sales for a rare climb up the charts in its third week, according to studio estimates on Sunday.
Vampire romance "The Twilight Saga: New Moon" dropped one place from last weekend to No. 2 with $15.7 million in ticket sales, and new release "Brothers," about soldiers returning home from war, landed in third place with $9.7 million.
The rise of "The Blind Side" bucks the accepted Hollywood wisdom that a new film will claim the No. 1 spot in its first week, then drop down the charts in subsequent weeks.
But "Blind Side," starring Sandra Bullock in the feel-good movie based on a real-life story about a woman who takes a homeless boy and helps turn him into a football star, opened at No. 2 three weeks ago. Its cumulative ticket sales now stand at $129 million in the United States and Canada.
