Fifty Shades of Grey doesn't open until February 13, but fans are already scooping up their tickets on Fandango to the hotly-anticipated adaptation of the popular best-seller. The film is currently the fastest-selling R-rated title in Fandango's 15-year history, already outpacing several major hits.

Fandango's top-5 R-rated advance ticketers, in first week of sales (as of Friday, January 16, 2015):

Fifty Shades of Grey is also having the biggest first week of ticket sales on Fandango for a non-sequel film, since the first Hunger Games movie in 2012, which still holds the record. Theater owners are posting new show times each day on Fandango to meet the hot fan demand in all the fifty states. Here's what Fandango Chief Correspondent Dave Karger had to say in a statement about Fifty Shades of Grey.

"It's tracking to be Fandango's fastest-selling R-rated movie of all time. Very few books can claim true national phenomenon status - and Fifty Shades ranks with Twilight, The Hunger Games and Gone Girl as novels that entered the zeitgeist from coast to coast. Fans of the book have been waiting for years to see their favorite sexy characters come to life on the big screen, and they are clearly fueling our sensational advance sales."

At the end of December 2014, Fandango surveyed more than 1,000 ticket-buyers, asking them which 2015 films they're most excited to see on the big screen. Fifty Shades ranked among the top four films, along with Star Wars: The Force Awakens, Avengers: Age of Ultron and The Hunger Games: Mockingjay Part 2, while Fifty Shades star Jamie Dornan was voted "Biggest Male Breakout Movie Star of 2015."
