Movie fans have bookmarked the Facebook drama "The Social Network" as their weekend favorite.
David Fincher’s saga about personality clashes and legal feuds among the website’s founders took in $15.5 million to remain the No. 1 film for a second straight weekend. "The Social Network" raised its 10-day total to $46.1 million.
Debuting a close second with a so-so $14.6 million weekend was the romance "Life as We Know It," starring Katherine Heigl and Josh Duhamel as sparring guardians to an orphaned girl.
The horse-racing drama "Secretariat," starring Diane Lane, also had a so-so debut, coming in at No. 3 with $12.6 million.
Opening a weak No. 5 with $7 million was Wes Craven’s serial killer thriller "My Soul to Take."
