Scenes were being filmed in Nice, France at the same time of the Nice terror attacks in July 2016.

The cover for "Fifty Shades Freed" is the exact opposite of "Fifty Shades of Grey". For the first movie cover Anastasia is the one with her arms up while Christian is the one about to kiss her, for this movie cover Christian is the one with his arms up while Anastasia is about to kiss him.

Some of the filming was done at Canadian singer-songwriter Sarah McLachlan's home.

There was talk that Jamie Dornan wouldn't reprise his role as Christian Grey but those rumors were put to rest as of February 25th 2015 when his agent stated he was devoted to the sequels.

Kim Basinger was set to return as series antagonist Elena Lincoln, even briefly appearing in the trailers, but her scenes were ultimately cut from the final edit.

Third and final chapter of the Fifty Shades trilogy.

In the book, written by E.L. James, Kate has a brother named Ethan who ends up dating Mia. He is not in the trilogy.

Dakota Johnson's fourth consecutive movie to debut on Valentine's Day weekend. The first was Fifty Shades of Grey (2015) , the second was How to Be Single (2016), and the third was Fifty Shades Darker (2017).

The shortest of this series, runtime being at 105 minutes, the second movie being at 118 minutes, and the first being at 129 minutes. So it goes in the order of the series.

Second Dakota Johnson movie to have a Hailee Steinfeld song in its soundtrack. The first was How to Be Single (2016), which also starred Steinfeld's Pitch Perfect 2 (2015) co-star, Rebel Wilson.

To create Gia Matteo, Arielle Kebbel chose red well-manicured nails to represent the elegant control of her character. As seen on The IMDb Show (2017).

The Pharmaceutical Sciences Building at the University of British Columbia in Vancouver, Canada serves as the exterior of the hospital that Ana wakes up in. Other locations on the university campus appeared in the first movie.

The book Christian is reading as he and Ana lounge on a beach chaise early in the film is called "The Hawk and The Sea" by Peter Bodnarus. There is no such book title in print (that I could find) and Peter Bodnarus is a well known Hollywood Art Director not a novelist. Perhaps the title is a nod to the hawk-like eye Christian keeps on Ana. This book is also a title that can be seen in Fifty Shades Darker during the board meeting where Ana gets the (at the time) temporary promotion. This may also show Christian's interest not only in SIP, but Ana"s work.

The actors who played "Ray" and "Liz" also appeared on multiple episodes of Californication.

At the end of the movie it is shown that Anastasia and Christian have a son and that she is pregnant again. Although is not shown in the movie, their son's name is Theodore Raymond Grey and the baby she is carrying it is girl, planned to be named Phoebe. It actually is shown after a few credits are played.

A nod to Bella's Meadow in the 'Twilight' series can be seen when Christian goes to visit his birth mother in the graveyard at the end of the movie. The description of the flowers in 'Twilight' match the ones found in the cemetery.

In the book, Ray (Ana's father) was in a bad car accident. They did not have this in the movie.

In the book, Kate's brother, Ethan, accompanies the group to Aspen and is pursued by Christian's sister, Mia. He does not appear in the movie and his role was incorporated into Jose's character. However there is no romantic interaction with Mia.
