It took three weeks, but “Argo” finally found its way to the top of the box office.

The Warner Bros. thriller from director and star Ben Affleck made nearly $12.4 million the weekend, according to yesterday’s studio estimates. “Argo” had been in second place the past two weeks and has now made about $60.8 million total.

Debuting at No. 3 was the sprawling drama “Cloud Atlas,” which made a disappointing $9.4 million.
