This Life of Mine is the seventh feature directed by
Sophie Fillières, who died in July 2023 shortly after completing the shoot of the film. She was hospitalised after the shoot and realised she would not survive the illness. She asked
Agathe and Adam Bonitzer, her children with
Pascal Bonitzer, and her producer Julie Salvador to oversee the post-production. A month after her death, Agathe and Adam assisted Francois Quiqueré in editing the film and used notes that their mother had written while in the hospital. Fillières wrote the film's screenplay five years earlier. In the production notes, she insisted that the protagonist Barbie was not autobiographical in nature. However, the lead actress
Agnès Jaoui commented that she often felt that she was portraying Fillières. During the production, she was made to wear the director's own clothes and her rings. The role of the therapist was portrayed the Fillières's real-life psychologist of 30 years. Salvador produced the film through her Paris-based company Christmas in July. ==Release==
