The Social network
The Facebook movie made about 2.9 million new friends this weekend. They spent an estimated $23 million on tickets to see 'The Social Network,' which debuted at No. 1 and earned an easy box office victory.

As expected, the movie's positive word of mouth, strong reviews (including much Oscar buzz), youth-appeal subject matter, and canny marketing (like that wonderfully viral trailer) ensured plenty of moviegoers would "Like" the Facebook drama. Among director David Fincher's movies, 'The Social Network' ranks as his third best debut, after 'Panic Room' ($30.0 million) and 'The Curious Case of Benjamin Button' ($26.9 million).

'Legend of the Guardians: The Owls of Ga'Hoole' finished a distant second but held up well in its sophomore weekend, losing just 33 percent of last week's business to finish with an estimated $10.9 million. Still the top choice among family fare and animated movies, 'Legend' has earned $30.0 million in two weeks.
