SOUS-SOL INTERDIT is an underground horror short film festival based in Paris, dedicated to bold, unsettling, and uncompromising cinema.
SOUS-SOL-INTERDIT will take place the October 31 2026. Screenings take place at the Théâtre STEPHANE GILDAS located at 16 rue Tolbiac, 75013 Paris.
Born in a literal basement, the festival embraces dark atmospheres, raw storytelling, and films that dare to cross boundaries, aesthetically, narratively, or emotionally. We are looking for horror in all its forms: psychological, visceral, experimental, strange, or poetic.
The first edition was sold out, with a packed room and a highly engaged audience. Our goal is not to become a massive industry event, but to remain a human-scale festival, where films are watched carefully, discussed passionately, and experienced collectively.
What we’re looking for :
Horror short films (fiction, experimental, animation, hybrid)
Strong visual identity and atmosphere
Singular voices and personal visions
Films that work on a big screen, in the dark, with an audience
Low-budget films are absolutely welcome, sincerity and creativity matter more than production value.
🎬 What selected filmmakers will experience
Selected filmmakers will be invited to take part in a unique, live cinema experience.
All selected films will be screened in a theater setting, in front of a real audience.
Films are discovered by the jury and the audience at the same time, during the screening.
After the projections, awards are decided live, including:
Jury Award
Audience Award
Filmmakers are warmly encouraged to attend the event to present their work, meet the audience, and take part in post-screening discussions.
While attendance is not mandatory, we strongly values the presence of filmmakers, as the festival is built around human encounters and shared cinematic moments.
Award winners will receive an official laurels pack and will be highlighted on the festival’s social media and website.
