Andre Aziman sobre la película:
I recall that when discussing his plans for the film, Guadagnino had told me that he would end the film with a shot of young Elio weeping before the camera. My heart sank. This was not at all what I had envisaged for the ending. The last pages of my novel sought to capture the lovers 20 years later as they reconnect and tell each other that, despite the years, they’ve forgotten nothing. Guadagnino told me that he had asked Sufjan Stevens to compose part of the soundtrack. I could not believe that a popular contemporary songwriter was particularly adapted to my story, especially since I had hoped for Haydn. But I kept quiet, thinking that perhaps the role of an author is never to intrude on someone else’s medium.
When I finally saw the film at the Berlin International Film festival, I was stunned. The ending captured the very spirit of the novel I had written in ways that I could never have imagined or anticipated, and as for the music, it resonated with the love of the two young men, so much so that the final scene with Elio and Sufjan’s song stayed with me long, long after I walked out of the movie theater and, as happens so rarely, into the next morning and the evening after that.
