seriousFilm is a Rotterdam based foundation for audiovisual production since 2004. The seriousFilm outfit is run by Koert Davidse (producer | director), Marc Thelosen (creative producer), and Edgar Kapp (production coordinator).
Documentary (co-)production is our main activity, but we also produce feature films, experimental shorts, documentaries, websites, animations, and installations. Co-productions are necessary to create a firm production and financial fundament, and allow for creative exchange between international professionals.
