Trivia

There was only one rehearsal before shooting. In multiple interviews, Timothée Chalamet and Armie Hammer said that director Luca Guadagnino asked them one day to come outside to do a rehearsal in the backyard of the villa. They walked to a patch of grass and flipped their scripts to a randomly selected scene to practice. When they opened the script, the page only read, "Elio and Oliver roll around in the grass making out." Chalamet and Hammer looked at each other and said, "Alright, let's go!" Just seconds into the making out scene, however, Guadagnino stepped in and directed them to act more "passionately." So they started making out and continued to do so, and no one told them to stop. Hammer said crew members had to pull them apart before the actors stopped, looked around and realized Guadagnino had just walked away, leaving them rolling around in the grass. This was their only rehearsal.

In an interview on Quotidien (2016), Timothée Chalamet revealed that Armie Hammer suffered wardrobe malfunctions from the shorts he wore throughout the movie, and his testicles had to be digitally edited out of some shots as a result.

During the hiking scene up to the waterfall, Elio and Oliver holler with excitement. In actuality, the screams were genuine reactions of discomfort from actors Chalamet and Hammer due to the frequent shocks from stinging nettle on their exposed legs. The entire mountainside was covered in it.

Director Luca Guadagnino told The Hollywood Reporter he was not interested in including explicit sex scenes in the film because the tone would have been very different from what he was looking for. He wanted the audience to completely rely on the emotional journey of these people and feel first love. He did not want the audience to find any difference or discrimination toward these characters.

Armie Hammer did not only star in the adaptation of "Call Me By Your Name," but he also lent his voice for the audiobook of André Aciman's original novel.

In an October 2017 interview with Variety, screenwriter James Ivory said that both Armie Hammer and Timothée Chalamet had it written into their contracts that they would not have to do full-frontal nudity, even though Ivory's screenplay stipulated that both characters would appear fully nude. He expressed his impatience with this in the interview: " I think is kind of a pity....it's just this American attitude. Nobody seems to care that much, or be shocked, about a totally naked woman. It's the men. This is something that must be so deeply cultural that one should ask: 'Why?'"

In the book, Elio is 17 years old and Oliver is 24. Timothée Chalamet was 20 years old when the film was shot, while Armie Hammer was 29. The film is set in Italy, and the age of consent in the country is 14.

Armie Hammer and Timothée Chalamet did not have to audition for the film. Chalamet was cast in 2013, after his agent introduced him to director Luca Guadagnino. When Guadagnino decided to do the film years later, he called Chalamet. Guadagnino cast Hammer after "falling in love with him" when the director saw him in The Social Network (2010), as he told Out magazine in October 2017.

Oliver kissing Elio's feet was improvised by Armie Hammer.

The film was largely filmed in chronological order, according to GQ Magazine.

Both the source novel and the original screenplay included much more explicit sex scenes (both gay and straight encounters) and full-frontal nudity but Luca Guadagnino excised several moments from the finished film unless they felt organic to the plot and themes of the film as he did not want any to feel gratuitous.

Director Luca Guadagnino told Billboard's Pop Shop Podcast that he and his team of filmmakers researched which songs would have been contemporary radio hits during the summer of 1983 in Italy and the summers before, and they used that to choose a number of the songs for the soundtrack. They also considered which time of day the songs would have been played, from the radio to the discotheque.

In the book, Elio is an Italian-American kid who speaks Italian and English. In the film, since Timothée Chalamet is fluent in French, his character speaks three languages namely, English, Italian and French.

The film in 2018 was nominated for 4 Academy Awards including Best Picture, Best Actor for Timothée Chalamet, and Best Achievement in Music Written for Motion Pictures (Original Song) for Sufjan Stevens for the song "Mystery of Love" and won one Oscar for Best Adapted Screenplay for James Ivory. Ivory, at age 89, became the oldest winner of a competitive Oscar surpassing the achievement of music composer Ennio Morricone at age 87.

Towards the end, when Elio's father is discussing Elio's friendship with Oliver, he says "Because it was him, because it was me." This is a quotation from Michel de Montaigne's essay "On friendship." Montaigne is discussing his friendship with an older man, though there is nothing in the essay to suggest that it was anything other than a platonic friendship.

The day-pack used by Elio in several outdoor scenes was Invicta's Jolly III Vintage, popular among school kids in Italy.

This film was based on André Aciman's acclaimed debut novel "Call Me By Your Name," published in 2007. Producer Peter Spears optioned Aciman's novel before it was published, after seeing an early galley in 2007.

Since it is the seventh night of Hanukkah, according to the Hebrew calendar, the final scene takes place on 1 Tevet 5744 or December 6, 1983.

In many scenes of the film, Oliver was wearing a tortoise Persol PO0649, and Elio was wearing a black Ray-ban Original Wayfarer, both classic sunglasses of Italian design from the 50s.

To add to the setting in the early 1980s, three references to contemporary movies are briefly visible: When Elio and Oliver are in town, a cinema poster in the background announces Tootsie (1982) and The Thing. When they are at the newsstand, a picture on the magazine rack shows the Millennium Falcon in front of a half-built Death Star, a scene from Star Wars: Episode VI - Return of the Jedi (1983).

"Later" is said 19 times by the end of the movie.

In an interview with the website Creative Screenwriting in May 2017, James Ivory revealed that initially, he and Luca Guadagnino would co-direct the film. The rights to the novel were optioned by some friends of Ivory who lived in upstate New York, in which one of them was an agent in Hollywood and the other was then a would-be producer. They asked Ivory whether he would be interested in being an executive producer on a film adaptation of the book if they were able to get it going, and Ivory agreed. Time passed, and they unable to get it going because they could not find anyone to direct that had a track record. They then found Guadagnino and he made the suggestion that he co-direct the film with Ivory. They asked Ivory if he would be willing to co-direct it with Guadagnino, and though he did not really know him, Ivory said, "Sure, but if I do that I want to have my own screenplay." Ivory did not want anybody else writing the screenplay if he were co-directing and he spent nine months writing it, and because of the screenplay they were finally able to raise the money to make the film. However, the French financier thought that it would be awkward to have two directors working together, so Ivory sold the rights to the screenplay to Guadagnino's company and the film was made by them.

Elio's white t-shirt with the cartoon character Fido Dido relaxing across the front is amusing as Fido Dido wasn't created until 1985 and became quite popular in the late 80's and early 90's.

Gabriele Muccino, Sam Taylor-Johnson and James Ivory were considered to direct the movie.

The film's two opening title cards read: "Summer 1983" and "Somewhere in northern Italy".

When Elio complains at the dinner table that he finds Oliver "arrogante" (arrogant) for saying "later," he is wearing a J. Crew Slim Secret Wash shirt with red and white stripes. J. Crew is an American company that was founded in 1983, the same year Elio and Oliver meet.

At the Academy Awards event when James Ivory won the Oscar and went on stage to accept the award, audiences could notice that he was wearing a shirt with a drawing of Elio's face.

According to director Luca Guadagnino, the decision to go away from the retrospective aspect of the book was made because he wanted to focus on the essence. He wanted the audience to immerse themselves in these characters and not have the story be driven by the consciousness of a third party or the narrator in another position in time. He wanted the audience to grow with them.

In the book, Oliver actually eats the peach Elio had fooled around with, and Elio cries because "no stranger had ever been so kind or gone so far."

In the book, Oliver visits the Perlman family again at Christmas and announces that he intends to marry next summer. In the movie version, Armie Hammer makes the announcement over the telephone when he calls the family from the US.
