Guillaume Malandrin (born on March 4, 1968) is a French film director , screenwriter and producer . He moved to Brussels after his studies at INSAS in the late 1990s . When he arrived in Brussels, at INSAS, in the image section, he thought he was entering a photography school and discovered with amusement that he was being taught how to record moving images. Little by little, he got into the game, met Michel Cauléa with whom he co-wrote the screenplay for Deux ramoneurs chez une cantatrice, Vincent Tavier (Ça c'est passé près de chez vous), and assiduously frequented the front rows of the Musée du cinéma, watching two films a day for more than two years. In 1992, he directed Qui déménage, an 18-minute romantic comedy produced by L'Atelier de réalisation de l'INSAS. Trained at INSAS , Guillaume Malandrin quickly became involved in the Belgian cinematographic landscape, notably by founding La Parti Production with Vincent Tavier , Stéphane Vuillet and Philippe Kauffman , a company with which he notably produced Aaltra by Gustave Kervern and Benoît Delépine , Komma by Martine Doyen , and Panique au village by Vincent Patar and Stéphane Aubier , which he co-wrote.

He works alongside his brother Stéphane Malandrin at the production company Altitude 100 located in Brussels.
