Guadagnino has deliberated over the idea of a sequel since the film's premiere at Sundance, when he said he realized the characters "could go beyond the boundaries of the film."[47] In October 2017, he said he hoped to make a sequel in 2020 that might be in the style of François Truffaut's The Adventures of Antoine Doinel series, telling the story of Oliver and Elio as they age. "If I paired the age of Elio in the film with the age of Timothée, in three years' time, Timothée will be 25, as would Elio by the time the second story was set", he said.[245][246] In the novel, Elio and Oliver reunite 15 years later when Oliver is married. Guadagnino said that in the sequel, "I don't think Elio is necessarily going to become a gay man. He hasn't found his place yet ... I believe that he would start an intense relationship with Marzia again."[247]
Guadagnino has expressed interest in the politics of the 1990s, saying, "It is the time of the fall of Communism and the start of the new world order and so-called 'end of history' that Francis Fukuyama established then ... the beginning of the [Silvio] Berlusconi era in Italy and it would mean dealing with the [first Gulf War] of Iraq."[247][248] In November 2017, Guadagnino shared his intention to make a series of five films, in which the audience could "see those actors grow older, embodying those characters."[47] A month later, he was reported to have begun writing a script for a sequel that would reveal more about Oliver and resemble Michael Apted's Up series.[249][250] Hammer and Chalamet have expressed interest in appearing in a sequel,[251] but Ivory appears to be dismissive, saying about the idea of sequels, "that's fine, good. But I don't know how they're going to get a 40-year-old [Chalamet]!"[43]
In January 2018, Guadagnino revealed the sequel will be set "right after the fall of Berlin Wall and that great shift that was the end of ... the USSR",[19] and that the first scene in the film could depict Elio watching Paul Vecchiali's Once More (1988)—the first French film to deal with AIDS—in a movie theater.[252] In March 2018, Guadagnino confirmed he will work with Aciman on the sequel, which will take place "five or six years afterwards" with "a different tone" than the first film.[253] He also said that Hammer and Chalamet would reprise their roles with a different backdrop, where they "go around the world".[253] Hammer said he was pitched the script by Guadagnino, saying: "it's not a finished script, but he's got all the ideas for it".[254] In April 2018, Aciman said in an interview for The Sydney Morning Herald that he and Guadagnino were "not sure" about the sequel, saying "[Guadagnino] has quite a few projects in line and so do I. So we are flirting with each other about the sequel but I don't know if we are very serious."[255] In July 2018, Stuhlbarg said that Guadagnino and Aciman were excited about the project and that the director was "serious" about it. He expressed enthusiasm to reprise his role in the sequel, saying "I think it would have to be some kind of unique thing from what it was, but I would absolutely be game for trying."[256] Two months later, Hammer said of the sequel in an interview for Variety: "It will happen because there are already people working on it and trying to make it happen."[257]
In an interview for Time in October 2018, Chalamet compared the sequel to Richard Linklater's Boyhood (2014) and said that Hammer, Aciman and Guadagnino were all intended to return for the next film.[258] That same month, Guadagnino revealed that he has asked Dakota Johnson, a frequent collaborator of his, to play Oliver's wife in the sequel. He described her character as "a New England kind of hoochie woman" who might also have children with Oliver.[259] He said that the film would be "a new chapter in a chronicle" about the characters, rather than a sequel,[260] and it might take some time to develop due to the busy schedule, saying "I have not been able to luxuriate in anything but the promotion of Suspiria ... I didn't have space of mind and the real, actual time to put ideas on the table and think of things."[260] "The only problem is the title," he said; "It cannot be Call Me by Your Name Two".[259][261] At the SCAD Savannah Film Festival in October, Hammer said that Guadagnino had laid out a potential plot for the sequel and it might be a few years away, saying "[Guadagnino] wants to wait so that we age a bit more so that gap makes sense, kind of like a Linklater thing."[262] In an interview with Dazed in November, the director said about the sequel, "It's a delicate flower that is blooming very slowly. And so I think it's not the time to collect it and put it into a vase."[263]
In November 2018, Ivory confirmed that he wouldn't return for the sequel and said that Aciman thought "it was not a good idea".[264] Less than a week later, Aciman, however, said he was in fact writing a sequel to Call Me by Your Name.[265][266] The novel, titled Find Me, was officially confirmed on March 20, 2019, and was released on October 29 by Farrar, Straus and Giroux.[267] Also in March 2019, Hammer revealed that the film isn't formally in the works, and he hasn't had explicit conversations with either Chalamet or Guadagnino about it. He also felt the potential sequel might not match the expectation, saying, "It felt like a really perfect storm of so many things, that if we do make a second one, I think we're setting ourselves up for disappointment. I don't know that anything will match up to the first ... I'm like, 'That was such a special thing, why don't we just leave it alone?'"[268]
In March 2020, Guadagnino confirmed a sequel film in an interview with Italian newspaper la Repubblica. In the interview he also confirmed that the full cast of the original film, including Timothée Chalamet and Armie Hammer will be returning. He also stated in the interview that he was due to meet with an unnamed American writer to discuss the sequel, however it was postponed due to the COVID-19 pandemic.[269] In a GQ interview in September, Hammer was asked again about the film's progress and said, "I've been talking to [Guadagnino], but we haven't got into it. I haven't even read the book. I know Luca hasn't got a full script yet, although he knows what he wants to do with the story, so I don't know how similar or dissimilar it will be to Find Me the novel. I know if we end up doing it, it’s more important for me to focus on Luca’s vision than to focus on Find Me."[270]
A series of allegations against Hammer of emotional abuse and cannibalistic fetishism in early 2021 – resulting in Hammer's removal from nearly all upcoming projects – have raised doubts about the prospects of a sequel,[271] but actor Michael Stuhlbarg hopes that the film will still be made.[272] In May 2021, Guadagnino suggested in an interview with Deadline that a sequel was no longer in his priorities.[273] In the interview, he hinted that, beyond the complications related to Hammer's scandal, Chalamet and himself would be busy with other films in the near future which has led him to put the sequel project aside.
