Hazar Ergüçlü’s latest film is moving from one major festival stage to another with serious momentum. MUTTER: The Diary of a Mother, written and directed by Alphan Eşeli, has earned international attention since its world premiere at the 2026 Tribeca Festival. Now, after its Turkish premiere at the 33rd Adana Altın Koza Film Festival, the atmospheric horror drama heads to the Sitges Film Festival in Spain, where it enters the Official Fantàstic Competition.
The timing could hardly be stronger for Ergüçlü. Her performance as Gül has already earned her the Best Actress award at Adana Altın Koza, giving the film a major piece of recognition before its Spanish festival appearance. For a Turkish genre film built around motherhood, fear, isolation and transformation, the journey from Tribeca to Adana and now Sitges places MUTTER firmly on the international festival radar.
MUTTER: The Diary of a Mother Arrives at Sitges
Sitges is one of the most important festivals for fantasy, horror and genre cinema, making it a particularly fitting destination for Eşeli’s film. The official festival listing places MUTTER in the Official Fantàstic Competition and identifies it as a 2026 Turkish production running at 99 minutes. The festival also describes it as a feverish contemporary folk tale in which tenderness and terror exist side by side.
Ergüçlü and Eşeli are scheduled to attend the film’s Sitges presentation. The festival programme lists a screening at Sala Tramuntana Meliá on October 12, followed by another at Sala Auditori Meliá on October 13.
For MUTTER, Sitges is more than another stop on a festival itinerary. It is an important test in front of an audience that understands the language of horror, fantasy and unsettling genre storytelling. That context can help the film reach viewers who might otherwise overlook a Turkish independent genre production.
A Horror Story Built Around Motherhood
At the center of MUTTER is Gül, a woman whose life changes dramatically after she gives birth under traumatic circumstances. The child she brings into the world is not human, creating an immediate collision between maternal devotion and fear.
The official Tribeca synopsis presents the premise in deliberately stark terms: Gül gives birth to an inhuman, alien-like creature, her partner leaves, and she chooses to protect the newborn. From there, the film moves beyond a conventional creature feature. The real tension comes from the emotional and psychological cost of Gül’s decision.
That distinction gives MUTTER its strongest dramatic hook. The creature may create the visual shock, but Gül’s attachment drives the story. As her physical and mental state begins to unravel, love becomes increasingly difficult to separate from obsession, sacrifice and survival.
Eşeli uses the Black Sea setting to intensify that feeling of isolation. Fog, remote roads and a harsh landscape become part of the film’s emotional architecture. The environment does not simply provide atmosphere; it reinforces Gül’s separation from ordinary society and makes her struggle feel increasingly claustrophobic.
Hazar Ergüçlü’s Award-Winning Performance
The Adana Altın Koza recognition gives Ergüçlü’s performance added weight. The actress won Best Actress for her portrayal of Gül, while the film also collected awards for editing, cinematography and art direction, according to festival coverage.
That recognition matters because MUTTER depends heavily on its central performance. Gül has to carry scenes that move between maternal tenderness, physical exhaustion, fear and psychological instability. The role requires restraint as much as intensity, particularly because the film’s unusual premise could easily overwhelm its human story.
Ergüçlü’s involvement also extends beyond acting. The official film site credits her as a co-producer, making MUTTER a significant creative project in her recent career.
From Tribeca to a Turkish Theatrical Release
MUTTER began its festival journey at Tribeca, where it screened in the Escape From Tribeca section as a Turkish-language feature with English subtitles. Tribeca’s official programme described the film as a drama, horror, mystery and thriller, while praising its distinctive approach to the creature-feature tradition.
That international launch has now been followed by the film’s Turkish festival premiere and its Sitges competition slot. The next major milestone is the Turkish theatrical release, scheduled for November 27, 2026.
For audiences interested in Turkish horror films, psychological creature features and festival cinema, the release offers a chance to see whether the film’s unsettling festival identity translates into a broader theatrical audience. Its unusual premise and strong festival credentials give it a clear point of difference in a crowded horror market.
Why MUTTER Deserves Attention
MUTTER: The Diary of a Mother stands out because it does not treat horror as an end in itself. Its supernatural premise provides a framework for examining attachment, alienation, grief and the limits of unconditional love.
The film also represents an encouraging example of Turkish genre cinema reaching major international platforms. Tribeca established its global profile, Adana confirmed the strength of its central performance, and Sitges now gives it another influential audience.
With Hazar Ergüçlü leading an emotionally demanding role and Alphan Eşeli shaping the film through a dark, atmospheric visual language, MUTTER has the ingredients of a genre title that can travel well beyond its home market. The November 27 release will reveal how Turkish audiences respond, but its festival journey has already established the film as one of the more intriguing Turkish horror releases of 2026.
Final Thought
MUTTER: The Diary of a Mother is shaping up to be one of the more intriguing Turkish genre films of 2026. With Hazar Ergüçlü’s Best Actress win at Adana Altın Koza and its place in the Sitges competition, the film has already built strong festival momentum. Its November 27, 2026 theatrical release will be the next major chapter and one worth watching for fans of atmospheric, psychologically driven horror.
