Stieg Larsson had planned to write ten books about Lizbeth Salander and Mikael Blomkvist, and the notes are in the possession of his partner, Eva Gabrielson. However, since they were not married, his father and brother inherited the rights to his literary estate upon his death, and the two parties never came to terms about the direction of the series. The family then hired another writer to create new stories.

It was announced in November 2015 that David Fincher, Daniel Craig and Rooney Mara would not be returning for this film.

With the story taking place in Stockholm, Claire Foy adopted a Swedish accent for the film with the help of linguistic coach William Conacher, who had already helped her create her royal accent for The Crown.

Before Claire Foy was attached to the film, Natalie Portman and Scarlett Johansson, originally considered for the title role in the previous film, were once again in talks to play Lisbeth Salander. Sony also considered Felicity Jones and Alicia Vikander for the titular role.

The director admits to being an admirer of Claire Foy since he discovered her in the series The Crown.

Follow up from David Fincher's 2011 film: 'The Girl with the Dragon Tattoo'. This jumps to the fourth story in the book series.

It is based on the novel of the same name by David Lagercrantz, and continues on the "Millenium" series created by Stieg Larsson, who passed away in 2004.

The color palette of the film is black (darkness), red (blood) and white (light and snow). In opposition to Claire Foy, who is black from head to toe, Sylvia Hoeks carry hair of an extremely light blonde, almost albino. The actress also faded up her eyebrows as much as possible.

While Fede Alvarez admits that he does not usually care about the appearance of his characters, the look of Lisbeth Salander was crucial in the film, especially her tattoo.

The director wanted to turn most of the stunts on the set, without resorting to visual effects or green backgrounds. For a stunt in a snow-covered car, the team used a "top rider", that is to say a fully functional car where the driver is sitting on the roof and the actor behind the wheel pretends to drive.

You can see a sticker of the Uruguayan football team 'Peñarol' in one of the scenes.

Fede Alvarez brought together director of photography Pedro Luque Briozzo, costume designer Carlos Rosario and composer Roque Baños with whom he had previously collaborated on his two previous films, Evil Dead and Don't Breathe.

Principal photography began in January 2018 in Berlin, and ended in April 2018, in Stockholm.

The film, a soft-reboot with different actors, is a sequel to David Fincher's The Girl with the Dragon Tattoo, and the second installment in the American-produced Millennium film series.

Millenium: The Girl in the Spider's Web is the adaptation of the book by David Lagercrantz, who took over the Millenium saga after the death of Stieg Larsson. Fede Alvarez's film is not a reboot of the saga, nor the direct sequel to David Fincher's feature film released in 2011.

The Girl in the Spider's Web had its world premiere at the Rome Film Festival on October 24, 2018.

Although the universe of the Millenium saga is crude and dark, costume designer Carlos Rosario has designed a more accessible Lisbeth.

Sylvia Hoeks plays a character who did not exist in the previous installments of the saga, although Stieg Larsson refers to it in his original novels. The Dutch actress, discovered by the general public in Blade Runner 2049, could be guided by her imagination on the set.

The main plot has several similarities with Mercury Rising (1998): both movies are involving with computers and high-tech, a defense's secret program, a kid with special mental capacities, a professional assassin who several times tries to kill the protagonist, a government's agent who tries to save the kid and a corrupt government's agent who tries to keep the program.
