Sandra Bullock's vehicle "The Blind Side" has ended its two-week streak as an underdog to North American box office leader, vampire romance "The Twilight Saga: New Moon" and brought home the title with an estimated 20.4 million dollars in tickets sales, projected statistics show Sunday.

Based on the real life of Michael Oher, an American professional footballer who owes his success to his adoption by Sean and Leigh Anne Tuohy (Sandra Bullock), the Warner Bros. uplifting film has received positive reviews from critics. Rotten Tomatoes reported that 74 percent of critics gave positive reviews, based on 112 reviews. The flick has taken in a domestic total of 129.3 million dollars over three weeks, according to North American box office authorities.

"The Twilight Saga: New Moon" still managed to stay on the second place with a projected 15.7 million dollars harvest, thanks to the loyalty of vampire-story fans and especially women who throng to theaters to get a glimpse of handsome actors. All told, it is expected to rake in 255.6 million dollars in sales over three weeks since it hit the screens in Canada and the United States.

Driving into the third place is "Brothers", a Lionsgate drama/war debut that grossed 9.7 million dollars. Featuring Tobey Maguire, it is based on Susanne Bier's 2004 Danish film of the same title.

Rounding out the top five most-popular films in the United States and Canada are:

No.4: "Disney's A Christmas Carol", with 7.5 million dollars this weekend and 115 million dollars over five weeks; No.5: "Old Dogs", Disney, 6.9 million dollars this weekend and 33.9 million dollars over two weeks.
