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.

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."

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.

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

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).

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

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 Wright's novel: one which departed from the source's original story, and another which stuck to it.

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.

Laura Linney replaced Kim Basinger.

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.

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

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.

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.

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

Both female leads in the movie are older than Jake Gyllenhaal. (Amy Adams-42 and Isla Fisher-41, while Jake is 36).

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.

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.

This is Jake Gyllenhaal's thirty-fifth film.

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

Nocturnal Animals is the 2nd film written and directed by fashion designer Tom Ford after A Single Man (2009).

Film debut of Robert Aramayo.

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

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)).

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

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

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 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 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.

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

Supposedly, Edward wrote his masterpiece in an attempt to make Susan love him again and then leave her just as she did twenty years ago.
