Watch on Soap2day. Produced and directed by Hurwitz for National Educational Television (precursor of PBS), Hurwitz uses biographer and Columbia professor, John Unterecker, to help him look for the poet, Hart Crane, in his work and in the memories of many of his contemporaries. In Search of Hart Crane, 1966, is one of the very first interview-driven documentaries and is still a masterpiece of the literary documentary film.
