David Gregory is a name synonymous with meticulous genre exploration, a trait that resonates deeply with physical media collectors. His directorial work often delves into the fascinating, forgotten corners of cult cinema and the painstaking processes behind their creation. Gregory’s commitment to preserving these cinematic legacies is evident in his acclaimed documentary features, offering insights that elevate standard bonus features to essential viewing for film historians. Collectors avidly seek out Gregory's films not just for their subject matter but for the unparalleled historical context they provide. His 2014 documentary, *Lost Soul: The Doomed Journey of Richard Stanley's Island of Dr. Moreau*, is a prime example, unraveling one of cinema's most legendary production nightmares.
