Box Office: 'Fifty Shades' Scores Record Valentine's Day Advance Ticket Sales

To boot, it's pacing to become the No. 4 advance seller of all time behind 'The Twilight Saga: New Moon,' the final 'Harry Potter' movie and 'The Hunger Games,' according to Fandango.

Is Fifty Shades of Grey turning into a datenight movie?

The R-rated Fifty Shades of Grey has become the top title of all time in terms of advance ticket sales for Valentine's Day, as well as for the Presidents Day weekend, besting Valentine's Day, according to online ticketing service Fandango.

To boot, it's pacing to become Fandango's No. 4 advance seller of all time behind The Twilight Saga: New Moon, the final Harry Potter movie and The Hunger Games.

MovieTickets.com is also reporting intense interest in Universal and Focus Features' R-rated adaptation of EL James steamy S&M novel, with advance sales accounting for 75 percent of its business for the long Valentine's Day and Presidents Day weekend (it's commanding 80 percent of all Fandango sales).

While women are expected to make up the vast majority of the audience, it appears that many are convincing their partners to make the movie a Valentine's Day destination. According to MovieTickets.com, 80 percent of tickets for Valentine's Day (Saturday) are being purchased by couples. That compares to 26 percent on Friday.

Fifty Shades, made for a relatively modest $40 million, is expected to gross $60 million or more over four-day holiday weekend, although Universal is being more cautious and saying $50 million-plus.

To date, Valentine's Day (2010) holds the record for best Valentine's Day/Presidents Day weekend gross in North America with $63.1 million.

Many box office experts believe Fifty Shades could outperform industry expectations, considering the massive awareness surrounding the film, directed by Sam Taylor-Johnson and starring Dakota Johnson and Jamie Dornan.

Either way, it will easily beat Matthew Vaughn's Kingsman: The Secret Service, starring Colin Firth, to top the box office chart.

Fifty Shades is likewise expected to do potent business overseas, or north of $50 million in its debut, based brisk advance ticket sales. Following its world premiere at the Berlin Film Festival Wednesday night, the $40 million film is opening virtually everywhere where allowed (Malaysia, a predominately Muslim country, has banned Fifty Shades, while other Muslim countries aren't likely to play it either).

James' Fifty Shades trilogy has been translated into 52 languages and sold more than 100 million copies worldwide.
