'Life' outruns 'Secretariat,' 'Soul' at box office

Heigl comedy earns $5.3 million; 'Social' still popular at No. 2

And they're off: In what's shaping up as a closely contested weekend, Warner's "Life As We Know It" took the early lead, bolting out of the gate ahead of the weekend's two other new wide releases: Disney's "Secretariat" and Universal's "My Soul to Take."

But Sony's "The Social Network" also showed continuing strength as it entered its second weekend. While it followed front-runner "Life" in second place for the day, positions at the top of the pack could still change as the weekend race plays out.

"Life," a baby-centric rom-com starring Katherine Heigl and Josh Duhamel, took the early lead. Appearing in 3,150 theaters, the PG-13-rated movie, co-financed by Village Roadshow, collected an estimated $5.3 million in North America.

"Network," Sony's drama about the founding of Facebook, continued to attract friends as it dropped just 39% from its opening Friday gross of $8 million. In the first day of its second heat, it took an estimated $4.9 million tally as its domestic gross to date rose to more than $35 million.

Randall Wallace's PG-rated "Secretariat," the inspirational tale about the Triple Crown winning horse, starring Diane Lane and John Malkovich, pulled into third place with $4.1 million in 3,072 theaters.

In fourth place, the 3D, R-rated horror tale "Soul," from writer/director Wes Craven and Relativity's Rogue Pictures, had to settle for $2.7 million in 2,572 locations.

Rounding out the top five was Warner's crime drama "The Town," which picked up a new $1.9 million as its domestic cume approached the $70 million mark.

Lagging behind the leaders was Focus' comedy "It's Kind of a Funny Story," which opened in just 742 theaters. Directed by Anna Boden and Ryan Fleck and starring Zach Galifianakis, the film garnered about $679,000 for the day.
