<P> Hammer and Chalamet both signed contracts that prohibited full - frontal nudity . Ivory, whose original screenplay had contained "all sorts of nudity," was dismayed by the decision, criticizing what he saw as an "American" attitude . "Nobody seems to care that much or be shocked about a totally naked woman . It's the men," he said . Guadagnino, who remained involved in the casting, chose actors based on their performances and chemistry, rather than choosing to "investigate or label" their sexuality . He said, "The idea that you have to cast only someone who has a certain set of skills, and worse, a certain gender identity in any role: that's oppressive to me". </P> <P> Principal photography on Call Me by Your Name lasted between 32--34 days . It began on 9 May 2016, shortly after A Bigger Splash was released in the United States, and completed in June 2016 . The process occurred quietly, with reports only appearing after filming had been underway for two weeks . The director's first cut of the film was four hours long . Post-production with regular editor Walter Fasano took only a month--between June and July, the fastest Guadagnino had edited . </P> <P> The film was shot primarily in Crema and the province of Cremona . It was shot during an unexpected historic rainstorm in Italy, described by the weather reports as a "once - in - century rain ." The pre-production in Crema was fast: a search for extras began there in March and April . Scenes from the nearby villages of Pandino and Moscazzano were filmed from 17 May, before moving to Crema on 1 June . Additional outdoor scenes were shot on 4 December 2016 . Several historical locations in the surrounding streets in Crema and Pandino were chosen during production, including the arch of Torrazzo at the Crema Cathedral . Businesses received compensation for financial losses caused by the closure, scheduled for 30 and 31 May . Two days' filming at the cathedral were postponed due to the weather . Production in Crema cost € 18,000, with a promotion campaign that cost € 7,500 . </P> <P> Filming also took place in the Lodigiano area near Crespiatica, and two small towns in the immediate vicinity of Crema: Montodine and Ripalta . The archaeological discovery scene was filmed at the Grottoes of Catullus in Sirmione, on the Brescian shores of Lake Garda . The trip to Bergamo was shot in multiple historical buildings, including the Bergamo Cathedral, the Santa Maria Maggiore, and the University of Sciences, Letters and Arts . The production team was only able to secure permission to film at the Cascate del Serio in Valbondione for half an hour, owing to concerns about security . </P>
