Swedish documentary filmmaker Jacqueline Zünd is set to world premiere her new film, Heat, at the Visions du Réel (VdR) doc festival in Nyon, Switzerland on April 20. The film explores themes such as climate change and the impact of this on the lives and relationships of individuals. It is set in the Persian Gulf, where temperatures exceed 50 degrees Celsius/120 degrees Fahrenheit and explores how heat affects character, economic dynamics, and social inequalities. The director's approach combines "societal relevance with a striking aesthetic" and includes cinematography by Nikolai von Graevenitz and edited by Gion-Reto Killias. Heat will be featured in the international feature film competition of the fest.
