<P> The actors lived in Crema and were able to absorb the rhythm of small town life . Guadagnino engaged deeply with the cast and filmmakers, often cooked and showed films for them in his house . Hammer and Chalamet, who did not have to do a screen test together, met for the first time during the production in Crema . They spent a month together before filming began, watched Mike Tyson documentaries and went to the local restaurants, to build character development . "We'd hang out with each other all the time, because we were pretty much the only Americans there, and we were able to defend one another and really get to know one another," Chalamet recalled . The actors rehearsed their scenes every night before shooting, and spent several days shooting completely nude . "I've never been so intimately involved with a director before . Luca was able to look at me and completely undress me," Hammer said . </P> <P> Stuhlbarg had prepared for the scene, in which Mr. Perlman delivered a education speech to Ellio, for months . "I was a little on eggshells because I'd been waiting so long to do it," Stuhlbarg recalled, "it's like holding your breath for two months ." It was filmed the day before shooting wrapped . During the dancing scene, Hammer had to perform in front of "50 extras off camera," with the music being turned down to record the dialogue . "That was not fun, I don't really enjoy dancing," Hammer said, "Here I am, dancing to this quiet music (...) I very quickly become the 6 - foot - 5 gangly guy that's very easy to spot from across the room ." </P> <P> Sayombhu Mukdeeprom, who had previously collaborated with Guadagnino in Ferdinando Cito Filomarino's Antonia (2015), served as the director of photography . Guadagnino and Filomarino developed an "exquisite and extraordinary" relationship with Mukdeeprom during the production of Antonia, the cinematographer's first non-Thai film . Lighting is an important factor in Mukdeeprom's work, as he needs the light to be engaged with the characters . In order to capture the Northern Italian summer atmosphere for Call Me by Your Name, he had to create completely artificial light, due to the heavy rains that lasted the entirety of the shoot . He also connected to the actors during the scene; when they finished shooting the first take of the confrontation between Oliver and Elio, he was crying in a corner of the room . The film was shot using a 35 mm lens, a decision influenced by the work of David Cronenberg in order to "solidif (y) the point of view ." </P> <P> The main location for the Perlmans' residence was an uninhabited 17th - century mansion in Moscazzano . The director initially wanted to buy the house but couldn't afford it, so he made a film at the place instead . Six weeks before production, the crew--including production designer Samuel Dehors and first - time set decorator Violante Visconti di Modrone--gradually decorated the house with furniture, objects, and decoration inspired by the characters . Much of the furniture, including the dishes and glassware from the' 50s, belonged to Guadagnino and Visconti's parents . "That made it cozy and personal," Visconti said, "I wanted to give it the sense of time passing by ." The Asian - inspired paintings, maps, and mirrors mostly came from an antiques store in Milan . The swimming pool used in the film was recreated from a watering trough common in the area . Guadagnino didn't want the film to "look like a reflection on the 80s, (...) when it becomes period ." His team did extensive research, with an assist from the residents of Crema, by entering people's houses and collecting their pictures of the' 80s . </P>
