Over the Columbus Day weekend, “The Social Network” made enough friends to hang on to the top spot at the box office for its second week. The film about the founding of Facebook added $15.9M for a domestic total of $46.4M. Coming in second was Katherine Heigl/Josh Duhamel starrer “Life As We Know It,” which brought in $14.6M in its debut weekend, considerably better than most recent romcoms have done.

Disney’s “Secretariat” came in a disappointing third with $12.6M. In its third week, “Legends of the Guardian” came in at number four with $7M, and the week’s other major debut, “My Soul to Take” took fifth with $6.9M. Finishing out the top ten were holdovers: “The Town” $6.3M, “Wall Street: Money Never Sleeps” $4.6M, “Easy A” $4.2M, “Case 39” $2.6M and “You Again” $2.4M.

The box office should get a well-needed injection of adrenaline next weekend, when “Jackass 3D” hits theaters, along with “Red” and “Conviction.”
