The Festival Chefs Op’ en Lumière has some fine surprises in store. This year, the out-of-competition screening of La Voix du Glacier Blanc reveals an innovative approach to mountain filmmaking.
Director Charles Lavilanie follows seven students from the IUT de Chalon-sur-Saône on their ascent of the Roche Furio, on the Glacier Blanc in the Écrins massif.
Their project stands out for one central concern: how can alpine adventure and ecological awareness be reconciled? To meet this challenge, they surround themselves with two professors, two mountain guides and a former IUT student specialising in carbon footprint calculations. His mission: to measure and study their environmental impact with precision. His professional expertise in this field brings a scientific dimension to the project, making it possible to quantify the impact of every decision in concrete terms.
The preparatory phase lays the foundations for their approach: calculating the carbon cost of transport, food and equipment, while seeking alternatives to reduce their ecological footprint. This rigorous methodology transforms the expedition from a simple mountain film into a genuine field study of environmental responsibility.
The ascent itself becomes a testing ground for their convictions. Each technical choice — from equipment to the route taken — is weighed against its environmental cost. The film captures these constant negotiations between the desire for adventure and the imperative of responsibility.
But the project goes beyond a simple accounting of their carbon footprint. It raises a fundamental question about our relationship with nature: can we continue to explore these spaces while preserving them? The students discover that ecological awareness does not diminish the intensity of the experience — on the contrary, it enriches it with an additional dimension of meaning.
The film also addresses the challenges of shooting in a mountain environment while minimising the crew’s impact. The choice of lightweight equipment, the rationalisation of takes and the optimisation of travel become integral parts of the creative process.
The result is a film where technical constraint becomes creative force, where ecological awareness feeds the narrative. These adventurers reinvent not only their relationship with the mountain, but also the way we film it.
