Mathilda R. Ström

French-Swedish writer, filmmaker, and art therapy practitioner

Devoted to crafting stories and characters

THE FOUNDER OF LA PORTE ROUGE

Trained in screenwriting and storytelling, I have been developing my dramaturgy over the past years by moving fluidly between cinematic, literary, and sometimes choreographic languages — exploring characters and stories in multiple forms.

As a child with an overflowing imagination, I expressed myself early on by shaping the imaginary tales that filled my mind — through writing plays or poetry, words became a way to give form to what needed to be spoken.

As I grew older, I naturally turned toward cinema. At first, I devoted myself to acting, notably during my training at Cours Florent in Paris, where I was able to embody a wide range of characters — both female and male, from Miss Julie to Roberto Zucco. Very soon, the urge to construct stories pushed me behind the camera. I began writing screenplays and directing short films, with my very first winning the Jury’s First Prize in Paris at EICAR, the film school where I shaped my cinematic voice. My latest short film, The Flow (2024), a danced fiction, was presented at the InShadow Screendance Festival in Lisbon at the end of 2024.

I then worked for several years in the Scandinavian audiovisual industry, mainly in Stockholm, as a production manager, screenwriter, director, and producer. More recently, I have returned to literature, developing novel-writing projects close to my heart, alongside children’s stories — created independently or through the “heroic creation” serious games I designed: therapeutic journeys intended for children and adolescents, as well as for people in difficulty who need to rediscover themselves and reframe the challenges they face.

As an art therapy practitioner and artist passionate about research, psychology, and neuroscience, I have created a laboratory at the crossroads of artistic creation, playful pedagogy, philosophical reflection, and creative therapy. It is the fruit of my aspirations and my will to build a project with meaning — one that allows me to do what I love most: create, explore, and share.
