His longest film, Het vertraagde vertrek (The Confinement of Space), whose screenplay he co-wrote with experimental writer Jacq Firmin Vogelaar, began with an investigation into how spaces condition people, but quickly took other directions. Filmmaker and writer decided to write each scene after viewing the footage shot for the previous one, which meant proceeding without a complete vision of the whole. This led to new themes and characters, and a difficulty in organizing the material, resulting in nine different cuts.
