Once You Know is the intimate journey of director Emmanuel Cappellin across a world at the edge of climate-induced collapse. His voyage into this uncharted territory is that of a whole generation, turning to climate scientists, local democracy, grassroots initiatives and mass rebellion in the courageous search for an exit.
Emmanuel Cappellin worked with Oscar-winning film animator Frédéric Back after taking Environmental Studies at McGill University and Film at Berkeley. Emmanuel now shoots for television (ARTE, France3) and cinema, collaborating with Yann Arthus-Bertrand on releases such as Human (2015). Once You Know is his first feature documentary.
Film Review: This intimate yet undeniably ambitious documentary serves as a wake-up call to a planet on the brink of climate-induced collapse. Director Emmanuel Cappellin travels the world to see how environmentalists are facing up to the inevitable global catastrophe. Cappellin’s film boldly tackles the big questions confronting everyone today, as population growth and diminishing resources further the trajectory towards collapse of everyday life as we know it. It acts as both a gut-punch and a salve, as his conversations with climate change activists - all influential contributors to the IPCC reports that fuelled the landmark 2015 Paris Agreement - seek to understand how to temper that “toxic knowledge” with collective action and a glimpse of hope. Winner of this year’s Jury Prize at the Hong Kong International Film Festival, this poetic and haunting documentary deftly balances global fears with our own personal uncertainty - and hints at a future where individual and collective resilience can offer some hope in the acceptance of unavoidable and fundamental change. An important film that’s guaranteed to stay with you long after you’ve witnessed it. Adam Mattera
