The film sees Jamie Dornan and Dakota Johnson return as billionaire Christian Grey and Anastasia Steele, the woman he introduces to his obsession with BDSM.

Here are nine things you need to know about the film:  

1. Ana and Christian make two visits to the Red Room. The first for Christian to demonstrate a nipple clamp on Ana’s finger, the second time to consummate their relationship with leather wrist restraints, a red blindfold and massage oil.

2. Ana wears the world’s most stubborn lipstick. She draws a box in her red lipstick on Christian’s cigarette burn-scarred chest to represent his boundaries. A few days later, the box is still there, unsmudged.

3. Kim Basinger looks sensational. The 63-year-old Oscar winner still sizzles as the “Mrs Robinson” character who seduced Christian at the tender age of 15.

4. Rich people shower in their clothes. It’s too much effort for Ana and Christian to strip off before heading into the shower so they get soaking wet in their designer togs.

5. Dakota Johnson pays tribute to her mother. In a cute touch, screenwriter Niall Leonard added a scene that replays word-for-word a scene from Oscar-nominated drama Working Girl, which starred Johnson’s mother Melanie Griffith.

6. Beautiful people don’t hurt. Despite all of the spankings and rough sex, Ana doesn’t have a single bruise or welt on her body and Christian survives a near-death experience without a single cut.

7. Rita Ora actually speaks. Her character, Christian’s sister Mia, even has a scene with Ana in which she debates what to buy her brother for his birthday and settles on a luminous tie.

8. Christian takes pride in the appearance of his Red Room. There isn’t a speck of dust in the Grey play room which compels Ana to question if housekeeper Mrs Jones is employed to tidy up: “Does she dust in here?

9. The hidden trailer. A 10-second teaser trailer for Fifty Shades Freed is hidden in the end credits so don’t leave the cinema early.

Fifty Shades Darker is released in UK cinemas on Friday February 10.
