From Wikipedia, the free encyclopedia. Martin Koolhoven (born April 25, 1969 in The Hague) is a Dutch film director and screenwriter.

Born as Martinus Wouter Koolhoven, Koolhoven graduated from Dutch film school in 1996 and almost immediately made an impact on the Dutch film industry with his 53 minute television film Duister Licht ("Dark Light") in which the slaughtering of a pig was shown. The film was nominated twice at the Dutch Film Festival. It was his next (and first feature length) film however that established his name, also outside of the Netherlands.
