Although he is known as a fashion designer, director Tom Ford chose to leave the costuming in the film strictly to the costume designer. Not a single Tom Ford product appears in the film, as Ford "didn't want a commercial."

Focus Features paid $20 million for global distribution rights after a heavy bidding battle in Cannes. This is the highest amount ever paid for a film at a festival.

Aaron Taylor-Johnson was cast as Ray Marcus after Tom Ford had dined with Aaron and his wife and longtime Ford friend Sam Taylor-Johnson. Aaron did not think he'd be suitable for the part at all, but over the course of dinner Ford saw a glimmer of something that he found intriguing in Aaron's facial expressions as he recounted a story at the dinner table. He then won a Golden Globe Award for his performance.

Tom Ford personally groomed Aaron Taylor-Johnson's facial hair for his creepy Ray Marcus character.

Laura Linney plays Susan's mother in a flashback scene when Susan was a college student. In real life, she is only ten years older than Amy Adams who portrays Susan.

Based on the book: "Tony and Susan". The book that Edward Sheffield writes in the book is called "Nocturnal Animals" (so the writer chose that title).

Most of the film takes place through the point-of-view of Susan. This includes her physical perception of the characters in Edward's novel while reading it. This would explain why the character of Tony looks like Edward himself which is due to Susan mentally casting Edward's likeness onto Tony.

Tom Ford edited this film at his London design studio where he would bide his time between his fashion fittings and editing for 4-5 hours daily.

With Aaron Taylor-Johnson's Golden Globe win for this movie, it marked the first time in more than 40 years that a Golden Globe winner in the Best Supporting Actor category hasn't secured an Oscar nomination (however, Taylor-Johnson's co-star Michael Shannon managed to get the nomination). The last time this happened was with Richard Benjamin's win for The Sunshine Boys (1975). Benjamin's co-star George Burns also received an Oscar nomination for Best Supporting Actor, which he ultimately won.

Originally, Tom Ford intended to make two films based on Austin Wright's source material novel: one which departed from the source's original story, and another which stuck to it.

Joaquin Phoenix was considered for Aaron Taylor-Johnson's role, but eventually dropped out.

Art references in the film include; a Jeff Koons 'balloon dog' sculpture, a Richard Misrach photograph, a Mark Bradford piece (custom made for the film), an Aaron Curry sculpture and an Alexander Calder 'mobile' all in Susan's home; a John Currin painting in Susan's gallery office. Much of the work came from the director's private collection.

Tom Ford was looking forward to making a comedy before this film, but he has revealed it was so inappropriate that it's possible it will never be made.

Laura Linney replaced Kim Basinger for the role of Anne Sutton.

Amy Adams and Jake Gyllenhaal have been cast in another project called 'Ezekiel Moss' which would have been directed by Philip Seymour Hoffman. However, the project was scrapped after Hoffman's death in 2014.

George Clooney originally signed on as a producer, but ultimately backed out.

At the art show opening, when the plus-size nude models are shown lying face-down, the first one lies in a pose reminiscent of "Benefits Supervisor Resting", a famous nude painting of a similar sized woman, by British artist Lucian Freud.

Michael Shannon's Best Supporting Actor Oscar nominated performance was the only one in the category not in a Best Picture nominee that year.

The film cast includes four Oscar nominees: Jake Gyllenhaal, Amy Adams, Michael Shannon and Laura Linney. Shannon was nominated once before, but was also nominated for Best Supporting Actor for his role in this film.

Both female leads in the movie are older than Jake Gyllenhaal who was born in 1980 (Amy Adams was born in 1974 and Isla Fisher was born in 1976).

Director of Photography Seamus McGarvey stated that this film is his favorite project he's ever worked on.

The Damien Hirst "St. Sebastian, Exquisite Pain" is in Susan's office.

Unlike the film, in the novel, Susan doesn't cast Edward's likeness onto Tony when she's reading his book.

In the film, the story takes place in Los Angeles. In the novel, the story takes place in Chicago.

Susan and Edward were both from Hastings, Texas. Edward would later give Tony, Laura, and India the town's name that he and Susan were raised in as their surname in his novel.

Some parts of the musical score were clearly inspired in Philip Glass and Bernard Herrmann's style.

When Susan accidentally cuts her finger when she opens the package from Edward containing his manuscript, it's foreshadowing how Edward's novel will ultimately cut deep into her.

This film is the second film written and directed by fashion designer Tom Ford after A Single Man (2009).

In Edward's novel in the film, Tony's daughter's name is India. In the book, Tony's daughter's name is Helen.

Film debut of Robert Aramayo.

Jake Gyllenhaal and Jena Malone both starred in Donnie Darko (2001), though they share no scenes in this film.

As opposed to being an art gallery owner in the film, in the original book, Susan was a teacher.

In the film, Susan's second husband's name is Hutton. In the book, his name is Arnold.

Though they share no scenes, This is the third film Amy Adams and Michael Shannon have worked in together (following Man of Steel (2013) and Batman v Superman: Dawn of Justice (2016)).

Director Tom Ford's second feature film.

Even though they don't share any scenes, this film is the first film that stars Jake Gyllenhaal and Zawe Ashton. The second film is Netflix's Velvet Buzzsaw (2019). Gyllenhaal and Ashton share scenes in that film and similar to this film, Velvet Buzzsaw (2019) also involves the art world.

Jake Gyllenhaal and Graham Beckel previously appeared in Brokeback Mountain (2005).

Though, their characters, Susan and Edward are around the same age in this film, respectively, Amy Adams is actually six years older than Jake Gyllenhaal.

This is Amy Adams' third film released in 2016. The first two films are Batman v Superman: Dawn of Justice (2016) and Arrival (2016), respectively.

Amy Adams, Jake Gyllenhaal, Aaron Taylor-Johnson and Michael Shannon starred in comic book films. Adams and Shannon starred in Man of Steel (2013) and Batman v Superman: Dawn of Justice (2016) together, and Adams went on to star in Justice League (2017). Taylor-Johnson starred in Avengers: Age of Ultron (2015) and Gyllenhaal starred in Spider-Man: Far from Home (2019).

Amy Adams' character, Susan, has a daughter (played by Bobbi Salvör Menuez) named Samantha. Coincidentally, in the book-within-the-movie, the fictional version of Adams' character (played by Isla Fisher) has a daughter named India.

The film was released 23 years after "Tony and Susan", the novel the film is based on, was published. The novel was published in 1993.

In the novel, Susan had two children with her second husband. In this film, she had one child.

The film uses the word "fuck" 51 times.

In the original novel, "Tony and Susan", Susan and Edward had been divorced for 25 years. In the film, they've been divorced for 19 years.

Amy Adams and Isla Fisher, both of whom portray Jake Gyllenhaal's characters' love interests in this film, previously starred as zany characters in wedding-themed films. Adams starred in The Wedding Date (2005) and Fisher starred in Wedding Crashers (2005). Interestingly, both films were also released in 2005.

Tom Ford: [nude people shown in a somewhat surrealistic and dream-like manner at the beginning of the film] The film begins with nude, obese women dancing in slow motion. In A Single Man (2009), the film opens with a nude man floating aimlessly in the water.

The inspiration for some of the events in Edward's book can be seen in the flashback scenes. For example, when Susan is criticizing Edward's book and telling him he should give up writing, she is on a bright red sofa. In the book, when Tony's wife and child, Laura and India, are murdered, they're dumped on a bright red sofa. Similarly, when Susan splits up with Edward, the scene ends with him standing alone beside a green Pontiac car, the same car driven by the killers in the book.

Often mistaken for each other in real life, Amy Adams and Isla Fisher both play versions of the wife to Jake Gyllenhaal's characters, adding to the dueling nature of the film's storylines.

Tom Ford has established in interviews that the ending is intended to be interpreted subjectively by the viewer. Edward did not show up, either because he still loves her and it is too painful to see her again, or because she gave him the inspiration and strength that he needed to write his masterpiece and move on. It is up to the audience to decide that.

The color green shows up in crucial scenes throughout the film. This is linked to ill-fated situations. For example: In the "Nocturnal Animals" novel, the car that Ray and his gang drive is green. The car is used to drive Tony and his family off of the road, and kidnap his wife and daughter. Furthermore, Ray's cowboy boots throughout most of the film are bright green, most notably during the attacks. The "night vision" video of the baby on the phone is naturally green. When Susan imagines seeing Ray popping up on the screen, she drops the phone, thus breaking it in the process. When Susan breaks up with Edward in one of Susan's flashbacks, a parked green car is seen in the background as Edward solemnly walks alone. This is the same type of car that Ray and his gang used in his novel. In the flashback where Edward sees Susan getting in the car with Hutton, their car is green. This was after Susan had gotten an abortion without telling Edward and basically coldly cut off contact with him. At the very end of the film, Susan wears a green dress for her dinner date with Edward. Furthermore, at the restaurant she chose for the date, there are heavy uses of green in the aesthetics. Edward ultimately never shows up, thus leaving her alone and devastated.

Edward is never seen in present-day. Jake Gyllenhaal only appears as Edward in flashbacks and as Tony in the novel story line.

In the original novel, there is no mention of Susan aborting her and Edward's unborn child without telling Edward. During their marriage, she never became pregnant by him. However, this plot point was written for the film and it added more depth to the strained relationship between Edward and Susan.

During the scene where Susan breaks up with Edward due to her disillusionment over their marriage, he says to her, "When you love someone, you work it out. You don't just throw it away. You have to be careful with it, you might never get it again." Susan later deduces that this statement meant that Edward never found someone else after their divorce. However, this statement actually foreshadowed Susan herself ending up in a miserable, loveless marriage with her second husband, Hutton, and the popular ending interpretation, Edward himself ultimately rejecting her when he stood her up at the restaurant when she wanted to meet with him after she finished reading his novel.

It's theorized that supposedly, Edward wrote his masterpiece in an attempt to make Susan love him again and then leave her just as she did to him almost twenty years ago.

In Edward's novel, Tony's wife and daughter are discovered dead on a red sofa. Tony is in shock and broken-hearted over the discovery. In one of Susan's later flashbacks, she and Edward are arguing over his writing material. The whole time, she was sitting on a red sofa that looks similar to the red sofa in his novel. She was putting him down by doubting his ability to legitimately write and not make his writing about himself. These statements made him upset. He then leaves the room dejected saying that he only wanted her to like his material. Edward eventually used the red sofa in his book as a metaphor for when Susan broke his heart the first time. Also, possibly the real reason why he sent her a copy of his book was to actually prove to her that he can write and that writing, like art, does require the author to sort of put himself or herself into his or her work.

Susan is seen throughout most of the film wearing dark makeup and dark nail polish. At the end of the film, she removes her dark makeup and dark nail polish when she's getting ready for her dinner date with Edward. This symbolizes Susan removing her cold facade.

In one of Susan's early flashbacks, she is seen talking to her mother over dinner. They're discussing her relationship with Edward and her mother's disdain towards him due to her perceived notion that he's not worthy and he isn't successful financially. The mother comes across as a vapid, hard-to-please, and cold person. This scene implies, judging by their interaction, that Susan and her mother aren't very close. Ironically, Susan slowly became more like her mother as time went on during her relationship with Edward and afterward in terms of her cold demeanor. Furthermore, Susan's relationship with her own daughter, Samantha, is shown to be also strained thus possibly repeating the cycle.

Despite the ending being left up to interpretation, some viewers curiously thought that the reason Edward never showed up to his dinner date with Susan was due to him committing suicide. It was argued that after writing the book and sending a copy to his ex-wife, Edward was still too broken by her and couldn't face her to where he ended his life. Also, another reason for this theory is that in his novel, Tony, who clearly represents him, dies at the end partially due to his actions and some viewers viewed that as a symbol for Edward's own possible death. Others argued that this wouldn't make any sense due to the logistics and rationale of the situation as well as what ultimately occurred in the original novel that the film is based on. Even though Edward never shows up during the present, that doesn't necessarily mean that he's committed suicide and, what some have pointed out, since the film takes place mostly through Susan's point of view, it most likely meant that he has finally moved on from her. In the novel, the reason that he never shows up to the dinner date is due to him leaving town to promote his novel and he didn't let Susan know that he wasn't going to show up to their date.

At the end of the film, Susan takes off her wedding ring before going to the restaurant to meet with Edward. It's theorized that this implies that Susan's marriage to Hutton is over and she wanted to start a new relationship with Edward.

When Susan looks on the phone to view the baby monitor, she imagines seeing Ray popping up to the screen which makes her drop the phone. This is showing that the "Nocturnal Animals" novel is having a major emotional effect on her. Also, this shows Susan's guilty conscience over, what is later revealed, aborting her and Edward's unborn child.

Some viewers believed that Susan's daughter, Samantha, is Edward's biological daughter and Susan didn't get an abortion. However, that would not be the case due to the amount of time that passed since Susan ended her marriage to Edward and Samantha's age. Samantha is Hutton's biological daughter.

The flashback scene where Edward and Susan go to a quaint restaurant for dinner after meeting up and the scene at the end of the film where Susan is alone in a fancy restaurant waiting for Edward to show up for their dinner date mirror each other. In the flashback, we see Edward and Susan talking about the past, and she is shown to be happy as opposed to the present when she's sitting alone and depressed waiting for Edward.

In hindsight, most of the events that happened are Susan's fault and it shows that she's impulsive when it comes to the decisions she's made in life. For example: Susan was the one who automatically initiated the relationship between herself and Edward right after they had met back up since their childhood. And she did it too quickly. During the dinner scene between them in Susan's first flashback, Edward was taken aback when she suggested that he comes home with her implying that she wants to be intimate with him. She did this without taking the time to actually get to know him again and properly assessing whether he's the right romantic partner for her or not, despite being childhood friends with him. Susan didn't listen to her mother who warned her that she will end up hurting Edward. Despite her mother's cold demeanor, she knew that her daughter was impulsive when it comes to choices. Susan decided to cheat on Edward with Hutton after Edward was seemingly becoming "weak" to her. Susan decided that Edward was no longer worth her time and, as she did at the start of their relationship, she initiated the breakup and divorce. Edward was willing to work it out but she was adamant about ending their relationship for good. Susan decided to terminate her pregnancy in order to cut off any ties to Edward and had no intention of ever telling him of this action. Despite leaving Edward and marrying Hutton thinking that she'll have a better life, Susan is miserable many years after the fact and guilt had consumed her. Interestingly, Susan mentioned that several years after her divorce from Edward, she tried calling him at one point and he hung up on her.

Some have noted that Edward showing up just when Susan and Hutton were leaving the abortion clinic was too coincidental. Even though the film mainly takes place from Susan's point of view, it's speculated that after she broke up with him, Edward most likely suspected that she was cheating on him. At some point, he discovered her infidelity, and he followed her and Hutton the day she ended up having the abortion. Once he saw that they were at the abortion clinic, Edward put two and two together and realized that they were there for Susan to abort his and her unborn child.

It's theorized that Tony's wife, Laura, represents what Edward thought of Susan when they were together. And Ray represents what Susan truly is to Edward.

In the film, Susan states she feels bad that Edward hadn't gone on to get into another relationship or remarry. In the novel, Edward had actually eventually ended up getting into a relationship after his marriage to Susan had ended.

It's heavily noted that in Edward's novel, India, Tony and Laura's daughter, represents Edward and Susan's unborn child. Since Susan aborted their baby, Edward carried that pain of loss as a parent and metaphorically channeled it through the kidnapping, subsequent rape, and murder of India in his novel. There are a few scenes that showcase this notion. For example: During the scene where Ray and his gang are harassing Tony and his family, India keeps throwing insults at Ray to which Ray responds angrily to her. With this, Laura keeps saying to Ray, "She's just a kid." This symbolizes that Edward was expressing to Susan that their unborn child was "just a kid" when she terminated the pregnancy. Laura and India ended up being kidnapped by Ray and his gang. This symbolizes Susan leaving Edward while carrying their unborn child, hence taking his family away from him. At one point during the novel, Tony has a nightmare of Ray raping India which deeply disturbs him. This symbolizes Edward's anguish over the defilement of his unborn child during the abortion process that Susan willingly partook in.

In the "Nocturnal Animals" novel, Tony and his family traveled on a seemingly endless road that leads to nowhere during the night. This symbolizes how Edward and Susan's relationship ended up leading to nowhere and became dark due to the choices she made.

It's stated by viewers that Bobby Andes represents Tony's conscience and Edward's stronger half.

During the flashback where Susan and Edward met back up, she's seen carrying many shopping bags. When they decide to go to a restaurant to talk and catch up, Edward helps her by carrying one of the bags for her as they walk on. This shows that despite coming from wealth and having the financial means, Susan is a serious shopaholic. Also, since Susan is known to be constantly dissatisfied, she most likely ended up engaging in compulsive buying. At the beginning of the film, despite affluent appearances, Susan and Hutton are bankrupt and had to sell off many of their possessions. This implies that things like Susan's shopaholic ways most likely took a toll on their finances.

Susan stated to her receptionist and assistant, Alex, while talking about Edward that he used to call her a "nocturnal animal" due to her always having trouble sleeping. In Edward's novel, Tony ends up having trouble sleeping after the kidnapping, rape, and murder of his wife and daughter. This would also make him a "nocturnal animal", hence, the film's title. The film is based on the novel, "Tony and Susan", which is by Austin Wright.
