'The Blind Side' tops weekend box office

Now that all the teenagers have seen "New Moon," it's safe for grownups to go to the movies again.

After three weeks in theaters, "The Blind Side" topped the box office this weekend with an estimated $20.4 million, according to BoxOfficeMojo.com

The Sandra Bullock film finished No. 2 in its first two weekends as "The Twilight Saga: New Moon" dominated the box office, but it appears the vampire/werewolf saga has peaked, dropping this week to No. 2, with an unspectacular $15.7 million haul.

Still, Moon's domestic gross of $255 million ranks it among the all-time box-office champs.
