'No Strings Attached' Ties Up Top Box-Office Spot

LOS ANGELES (AP) — Audiences weren't afraid of committing to "No Strings Attached," making it the No. 1 movie at the box office in its opening weekend.

The romantic comedy from Paramount Pictures earned an estimated $20.3 million, according to studio estimates Sunday.

Ashton Kutcher and Natalie Portman star as friends who try to maintain a purely sexual relationship with each other, even as they find they're falling in love.

Last week's No. 1 movie, Columbia Pictures' action comedy "The Green Hornet," dropped to second place with $18.1 million.
