Marek Koterski only appears to be a well-known filmmaker in Poland. He is one of the country's major and highly rated cinema directors. However, little is known about his oeuvre as a documentary filmmaker. Koterski made documentaries in 1969-1986, setting social issues (poor condition of healthcare, drug addiction, antiwar posters) against the dissonance form of a film essay in 'Little Tenderness', 'The Future or The War Song'. The author points out the continuity of some staple components of Koterski's short films (irony, dramatised intervention themes) with his feature filmmaking. His nearly forgotten documentaries are not only the unusual testimony to the time they were made but also a surprisingly fresh and interesting example of the consistent development of the author's strategy of the future director of 'We Are All Christs'. The article has been written for a retrospective of Koterski's films at the 'Iluzjon' cinema of the Polish Cinema Archive.
