Marmottes la Guerre des Clans (2026)

Marmottes, la guerre des clans is a French wildlife documentary that looks at the surprising social lives of Alpine marmots in the Grande Sassière nature reserve. The film follows researchers who have been observing families of marmots for decades and reveals territorial conflicts, competition, family structures, and the pressures facing these animals.

Matthias Abrantes presents the colony almost like a miniature political drama while keeping the focus on scientific observation. Camera traps and long-term research footage allow the documentary to examine both the animals' behavior and the effects of a changing mountain environment.
