Moritz developed his interest in the work of
Oskar Fischinger while a student at USC in 1958. His early enthusiasm for Fischinger's work became the focus of his career: "I saw my first Fischinger film, and it popped all my buttons!" Moritz's first major critical work on Fischinger was published in
Film Culture, in an issue devoted largely to this extensive essay about Fischinger, in 1974. In 1969, Moritz had begun his decades-long study, aided by Fischinger's widow Elfriede, finally culminating in the major biographical work
Optical Poetry: The Life and Work of Oskar Fischinger (2004). (The title is an allusion to
An Optical Poem, a short film made by Fischinger for
Metro-Goldwyn-Mayer in 1937).
Optical Poetry is regarded as a major study of Fischinger's life and work. It received a Willy Haas Award as best book publication at
cinefest - International Festival of German Film Heritage 2004. Moritz had a long career as teacher and researcher of film and the humanities. He taught humanities and film history, and in the course of his career worked at a wide variety of institutions: Occidental College, the Otis Art Institute,
Pitzer College,
UCLA, USC, the American University Center (in
Calcutta,
India). In 1987 he began teaching courses on the "History of Experimental Film," "History of Animation" and "Theory of Comedy" at CalArts. He also worked at the
Creative Film Society (now-defunct), and at radio station KPFK, as a film and music critic. As a film curator, he programmed screenings at a variety of Southern California venues including Theatre Vanguard. He was also involved in film preservation, for which he received an award from Anthology Film Archives. Moritz was himself a filmmaker, making 34 experimental films during his lifetime. He was a published
poet, and two of his plays were produced. His performance piece
The Midaswel Show was staged for several performances. His most significant contributions however are widely thought to be in the criticism and history of abstract film, experimental film, animation and visual music, as well as his promotion of little-seen films, which he had screened to audiences worldwide. ==Further reading==
