Koert Davidse

Koert started his career as a script writer for documentaries and feature films. Since the end of the 1990s, Koert has focused on directing documentaries with subjects that fascinated him personally: often about people outside of the mainstream
in 2002 he directed his first long documentary the Flood. His second long documentary Sybold van Ravesteyn: architect for eternity was seriousFilm’s first production

Koert is an experienced script doctor and coach of young talent. His James Avati – a life in paperbacks (1999) was released on video in the USA and Canada, and Telling Eyes (2002) was shown on ZDF and Arte


Marc Thelosen

As a creative producer Marc’s work experience ranges from programmer for the Image and Sound festival, producer of the World Wide Video Festival, and combining production and financial management for V2_Organisation (the Institute for the Unstable Media), to production coordinator of the Tulse Luper Network, part of Peter Greenaway’s the Tulse Luper Suitcases project.
One other thing: most of the artwork for seriousFilm is by Marc.
