No Strings Attached, the R-rated romantic comedy starring Portman and Ashton Kutcher, led the box office on Friday with $7.3 million, according to early studio estimates. On pace for a weekend score of about $20 million, Strings will be Portman’s first No. 1 movie since 2006’s V for Vendetta. And Strings‘ reasonable $25 million budget (compared to, say, Little Fockers‘ $100 million budget and The Dilemma‘s $70 million price tag) makes its victory all the sweeter for Paramount.

The Green Hornet claimed second place by dropping a not-too-shabby 49 percent for $5.1 million. The superhero comedy should finish the weekend with $17 million, bringing its cumulative gross to just over $62 million. The Dilemma also held up relatively well, slipping 47 percent for $3 million (and an estimated three-day result of $9.5 million). The British historical drama The King’s Speech remained in fourth place with $2.1 million — a fall of only 16 percent. And True Grit rounded out the top five with $2.1 million as well. (It trailed King’s Speech by an estimated $38,000). By the end of the weekend, the Western hit will have captured $137 million cumulatively.

In limited release, the Peter Weir war drama The Way Back took in a disappointing $375,000 from 659 theaters — a $569 per-location average. And the Ben Affleck corporate drama The Company Men registered $172,000 from 106 sites, for a per-theater average of $1,625. Check back here on Sunday for the complete box office report.
