Res nullius is a Belgian documentary examining the coexistence of humans and wildlife in the heart of Brussels. The film follows the trail of a wild boar spotted in a city park and uses the encounter to reveal how urban spaces function as ecosystems.
The documentary connects biodiversity, urban planning, and social questions while staying close to people working directly with wildlife and the city. Its perspective makes the ordinary city landscape feel unexpectedly wild and interconnected.
Res nullius has been shown through Belgian cinemas and documentary programs, with wider streaming availability dependent on distribution.
