Festival Atmosphères 2025: the free cultural program for the Fête de la Science

The Atmosphères Festival returns to Courbevoie for its 15th edition from October 8 to 12, 2025, offering free cinema, arts and science around the theme of sustainable development.

The Atmosphères Festival has established itself as a major cultural event in the Île-de-France region, attracting some 20,000 people to the Hauts-de-Seine every year. This 15th free edition, which takes place from October 8 to 12, 2025 in Courbevoie, confirms its position as a pioneering festival on sustainable development issues. Under the banner of the Fête de la Science 2025 and its theme "Intelligence-s", this edition explores the multiple forms ofhuman, artificial and livingintelligence.

In this International Year of Glaciers, the festival mobilizes the scientific community and artists around this crucial issue. Pascal Signolet, founder and general delegate, recalls that the event "brings together cinema, the arts and science to decipher the world and share innovative experiences". The ambition has remained the same for fifteen years: to inspire, raise awareness and encourage us to transform our lifestyles in the face of ecological and social emergencies.

The multidisciplinary program features several formats: cinema previews, workshops, debates, round tables and live performances. Screenings take place at several venues in Courbevoie: the Cinéma Abel Gance, the Centre Événementiel and theEspace Carpeaux. Some twenty films (fiction and documentaries) will be previewed, with the participation of the creative teams.
