The classical avant-garde lingers
In the years that followed, the classical avant-garde continued to dominate the experimental film programmes, and they remained the benchmark for new work. In the Netherlands, Bert Haanstra (Spiegel van Nederland), Emiel van Moerkerken (Koekoekswals), and the American filmmaker, Hy Hirsch (Gyromorphosis and Autumn Spectrum) still relied heavily on the pre-war avant-garde. But their films lacked the rigorous urgency of their predecessors; they were mainly playful, creative exercises.
