In a 2018 interview with Filmtopp,
Adrian Garcia Bogliano spoke about a specific casting choice and where the movie ended up being shot: "I wanted to bring back
Christina Lindberg to the screen. I'm a big fan of revenge films and many years ago I saw
Desenlace mortal (Thriller - en grym film) (1973) and was blown away! Out of all the other films in the genre, that one impressed me the most. After that, I watched pretty much everything she has starred in. I love her strange and unique presence. I talked to
Rickard Gramfors, her manager and the producer of Svart Cirkel (Black Circle), about making a movie in the United States. We were trying to develop the project for a couple of years but it didn't happen, so we decided to film something in Sweden instead."
