Two of James Cameron's closest collaborators, filmmakers Mike deGruy and Andrew Wight, have been killed in a helicopter crash in Australia reportedly while scouting camera locations for an upcoming documentary. deGruy was the director of undersea photography for Cameron's Last Mysteries of the Titanic and Wight was the writer-producer of the hit 3D film Sanctum. . In a statement Cameron said that the two men were like family. "They were my deep-sea brothers, and both were true explorers, who did extraordinary things and went places no human being has been. They died doing exactly what they loved most, heading out to sea on a new and personally challenging expedition, having fun in the way they defined it for themselves, which was hardship and toil to achieve something never done before. They were passionate storytellers who lived by the explorer's code of humor, empathy, optimism, and courage. Their deaths are a tremendous loss for the world of underwater exploration, conservation, and filmmaking."
