King of the Airs: Notes on a Friendship (2017)
Martin indulged in his excessive use of drugs. He recorded his frenzied life in his diaries while his friend Ivo passionately captured everything on film with his Super 8 camera. Both sought for the absolute – average was not an option. Through the lens of this journal, Ivo Zen tells the story of his generation, a story about friendship and the desire to fly higher than anybody else.
