Marc began as producer and programmer for the Image and Sound Festival (The Hague Film Foundation 1986-1990), an early and critically acclaimed festival on film and new media.
In the late 1980s he worked as production assistant and as post-production coordinator for film producer Allarts. After having produced 3 editions of the World Wide Video Festival in
The Hague in the ‘90s, he joined V2_Organisation (the Institute for the Unstable Media) in Rotterdam, where he combined financial controlling with programme production. In 2000
he returned to the film industry, first as production accountant, and later as production coordinator of The Tulse Luper Network (part of Peter Greenaway's the Tulse Luper Suitcases).
In 2004 he joined seriousFilm as creative producer.
