So who do you think topped the Box Office this weekend?  Give you a hint...  Natalie Portman was in this film!  No Strings Attached" is putting a Natalie Portman film at the top of box office for the first time in five years.  The romantic comedy -- which features Portman opposite Ashton Kutcher -- earned about 20-point-three-million dollars in its North American debut over the weekend.  In the film, Portman and Kutcher play characters who enter into a "friends with benefits" relationship that gets complicated. "The Green Hornet" starring Seth Rogen, meanwhile, slipped to second with 18-point-one million in ticket sales.  In third, was the Vince Vaughn-Kevin James comedy "The Dilemma," which pulled in an additional nine-point-seven-million dollars.  Rounding out the top five were the critically-acclaimed "The King's Speech" and "True Grit."  "The King's Speech," which recently won a Golden Globe for actor Colin Firth, raked in nine-point-two-million dollars, bringing its total North American box office to 58-point-six-million dollars.  "True Grit" starring Jeff Bridges wrangled up eight-million dollars this weekend.  That film's cumulative take is now north of 138-and-a-half million dollars.
