The Fifty Shades of Grey film adaptation earned $569.5 million worldwide—earning it the title of the second second highest grossing film of 2015 so far.

So the freaky success story of Christian Grey and Anastasia Steele, of course, warrants another movie, a sequel: Fifty Shades Darker.

Scheduled for a February 2017 release, Universal picutres chairman Donna Langley revealed yesterday during a Hollywood Reporter keynote Q&A session that this second installment will be "more of a thriller." Fifty Shades of Grey director Sam Taylor-Johnson, however, will not be returning to direct the sequel. 

Fifty Shades Darker is based on the second installment in the Fifty Shades trilogy written by E.L. James. In the book, we see the relationship between recent college grad Stelle and squillionaire businessman Grey intensify when jealous men (and women) enter the picture.
