His contributions to film history are particularly sought after in the collector's market, especially his involvement in The Conqueror (1956), which has garnered a notorious reputation due to its troubled production. Hoyt’s enduring legacy and the collectible nature of his films make him a fascinating subject for enthusiasts of physical media.
