Closure is a 2026 Polish documentary film directed and produced by Michał Marczak, with producers Monika Braid, Remi Grellety, Katarzyna Szczerba, and Karolina Marczak. The film had its world premiere in the World Cinema Documentary Competition at the 2026 Sundance Film Festival.
Premise After his teenage son, Krzysztof Dymiński, goes missing in May 2023, Daniel searches Poland's Vistula River, torn between fear that his son is dead and hope that he may still be alive. CCTV footage taken on the morning of his disappearance shows Krzysztof standing on a bridge, but not whether he jumped or walked away, and Daniel continues to investigate long after the police and local media have stopped searching.
Except for a final shot, the film uses no images of Krzysztof. The film's soundtrack includes a snippet of William Basinski's "The Disintegration Loops," which plays over the final scenes.
Release Closure premiered in the World Cinema Documentary Competition at the 2026 Sundance Film Festival. It has also screened at the True/False Film Festival, the Thessaloniki Documentary Festival, and Millennium Docs Against Gravity. It won Thessaloniki's Golden Alexander International Competition prize.
The film will compete at the 21st Rome Film Festival in 'Progressive Cinema Competition - Visions for the World of Tomorrow' in October 2026.
