In an interview with Elle magazine, actress Dakota Johnson revealed the intensity of the shoot had..."fucked [her] up so much that [she] had to go to therapy."
The music score is the debut score by Radiohead's singer Thom Yorke, who followed Radiohead and co-composers Jonny Greenwood and Phil Selway into film scoring. Greenwood is notable for scoring the films of Paul Thomas Anderson and Lynne Ramsay. Selway scored Let Me Go (2017).
Although Dario Argento gave permission to produce this remake, he was dismissive of the final results in an interview with Indiewire from August 2016: "Either you do it exactly the same way - in which case, it's not a remake, it's a copy, which is pointless - or, you change things and make another movie. In that case, why call it Suspiria ?". Argento also said that what's really absurd is that he was never asked about anything concerning the remake, nobody asked him about casting, locations or anything else. Luca Guadagnino told The Hollywood Reporter in 2018 that he's friends with Argento, who called him after he saw the film, and although he didn't want to relay Argento's reaction, he said it was a great call. In an interview with Italy's Radio Rai 1's "Un Giorno da Pecora" in January 2019, Argento said the film did not excite him: "It betrayed the spirit of the original film: There is no fear, there is no music. The film has not satisfied me so much." Argento added that it was "a refined film, like Luca Guadagnino, who is a fine person. Guadagnino makes beautiful tables, beautiful curtains, beautiful dishes, all beautiful..."
Unlike the original film, which uses exaggerated colors, Guadagnino conceived Suspiria as "winterish" and bleak, absent of primary colors.
