Sutton and BIll Burrud Productions. It tells the story of Colonel John D. Craig, a Hollywood cameraman who, in 1932, fell in love with the underwater world and dedicated his life to capturing it on film. Craig pioneered underwater photography and diving technology, creating some of the first underwater motion picture cameras and refining diving gear to explore deeper and more safely. His first dive in Baja, California used heavy Japanese hard hat equipment. Driven to share his fascination with the deep sea, Craig developed cameras and techniques that evolved from tripod-mounted units to lightweight 16mm cameras, making underwater motion pictures accessible and thrilling. Despite dangers, including equipment failure and life-threatening situations, he innovated self-contained underwater breathing apparatus (scuba), collaborating on helium-oxygen mixes to enable deeper dives. His career in military service included photographing atomic tests. Later he became a TV personality, producing "Kingdom of the Sea" and other series that explored sharks, sunken ships, and unique underwater experiences. Craig also trained divers for recreational, law enforcement, and firefighting, emphasizing safety and public service. Reflecting on his lifelong work, Craig expresses a continued romance with the sea, proud of his contributions to diving, underwater exploration, and film. The documentary closes by honoring Craig’s adventurous legacy. 00:00 Main titles. – Narrator introduces the story of Colonel John D.
