The working title for the film was "A Separation", but since multiple films are already called that the title was changed to "Anna and Tomas Getting a Divorce" - inspired by Jonathan Demme's Rachel Getting Married (2008).
This is the second time that director Marcus Carlsson and actor Magnus Sundberg have worked together. Their first collaboration was on the feature film Kärlek & vilja (2018).
The voice on the telephone belongs to Jennifer Karlberg, an actress who has worked with director Marcus Carlsson nine times, including twice on stage.
The opening shot of the film is similar to the opening shot of director Marcus Carlsson's feature film Kärlek & vilja (2018).
