Inferno (1980 Film) - Production

Production

In 1977, Suspiria had been an unexpectedly big box office hit for 20th Century Fox, released in the U.S. under their "International Classics" banner. Capitalizing on the commercial success of the film, Argento and Daria Nicolodi, who had co-written the screenplay, announced that Suspiria was only the first of a proposed trilogy, which they referred to as "The Three Mothers" trilogy. The basic concept of all three films is derived from Thomas de Quincey's Suspiria de Profundis, a sequel to his Confessions of an English Opium-Eater. A prose poem of the book entitled "Levana and Our Ladies of Sorrow", details how, just as there are three Fates and three Graces, there are also three Sorrows: Mater Lachrymarum (The Lady of Tears), Mater Suspiriorum (The Lady of Sighs) and Mater Tenebrarum (The Lady of Darkness). As the title suggests, Suspiria focused on Mater Suspiriorum, and the evil sister featured in Inferno is Mater Tenebrarum. The concluding chapter of Argento's trilogy, The Mother of Tears (2007), is about Mater Lachrymarum.

When Argento proposed Inferno as his follow-up to Suspiria, 20th Century Fox agreed to co-finance the production. The film was budgeted at USD $3,000,000, and producer Claudio Argento secured additional co-production money from Italian and German consortiums.

Nicolodi devised the original story concept, but received no on-screen credit for her work on the screenplay. Nicolodi explained that she did not seek credit because "having fought so hard to see my humble but excellent work in Suspiria recognized (up until a few days before the première I didn't know if I would see my name in the film credits), I didn't want to live through that again, so I said, 'Do as you please, in any case, the story will talk for me because I wrote it.'" Working from Nicolodi's original story notes, Argento wrote the screenplay while staying in a New York hotel room with a view of Central Park.
