‘Fifty Shades of Grey’ still (MTV)

Those who are planning to see “Fifty Shades of Grey” opening weekend might want to get their tickets like, right now. Five days after tickets went on sale Jan. 11, Fandango reports that it’s the site’s fastest-selling R-rated movie.

According to “The Hollywood Reporter,” the movie has already outsold advance tickets for “Gone Girl,” “Sex and the City 2,” and the second and third installments of “The Hangover.” It also logged the biggest first-week of ticket sales for a non-sequel since the first “Hunger Games” movie in 2012.

Clearly, the ticket sales indicate that there is some curiosity about BDSM amongst those who may lean more vanilla. It also speaks to a safe way to let one’s freak flag fly.

Or it’s a lot of people curious to see if it’s a total trainwreck.
