1. It's based on a book that you might well have heard of(01 of14)
Open Image ModalSimultaneously the fastest-selling book in UK history, while also being almost universally panned by critics for its seemingly terrible writing (apart from in the graphic, S&M-laden sex scenes, of course, which occur with staggering frequency, almost at the drop of a hat).

5. Other actors also make an appearance...(05 of14)
Open Image ModalBecause two hours of non-stop handcuffing and cries of "oh my!" do not a film make, other stars have been drafted in to help carry the so-called "plot".Eloise Mumford takes on the role of Anastasia's best friend, Kate, while José, who fans of the book will remember as another of her love interests, is played by Victor Rasuk.

Open Image Modal9. There are no jellyfish in it(09 of14)
Open Image ModalTrue, when we think "jellyfish", the first thing we think of isn't exactly "erotica", but director Sam Taylor-Johnson has admitted that if she'd had her way there would have been a sex scene involving jellyfish, as part of one of Anastasia's dream sequences.However, this ended up not going ahead. She told The Guardian: "there was a scene when we go into Anastasia's world and her head, and we just had these jellyfish on the screen. It was beautiful, very impressionistic. Everyone went, 'What the f**k are those jellyfish doing there?'" (credit:YASSER AL-ZAYYAT via Getty Images)

Open Image Modal15. Will 'Fifty Shades Darker' And 'Fifty Shades Freed' Be Getting The Film Treatment?(14 of14)
Open Image ModalThe short answer is "no", but presumably if the first film is a hit with critics and audiences (hey, hey, hey - we said "if"!), then the following two installments could be next. (credit:SAUL LOEB via Getty Images)
