A film enthusiast since his childhood, Grégory Morin left his native Berry region to study film in Paris at the Conservatoire Libre du Cinéma Français (CLCF). He then directed five offbeat, humorous, genre short films, including Paris by Night of the Living Dead (2009). He also directed music videos for Versatile Records and BR Films, as well as commercials for brands such as Ubisoft and Dark Dog. He has worked with screenwriter David Neiss on several feature film projects (Gaga, Le Prédicateur), but it was ultimately Flush that attracted the most interest from producers, particularly due to its original concept.
