The High Frontier: The Untold Story of Dr. Gerard K. O’Neill pays much overdue tribute to the figure many regard as the father of the space settlement movement. The film chronicles the life, career, and legacy of O’Neill from his origins as a young Navy sailor to his prime as one of sci-comm’s first rock stars. Rare archival photos and footage allow the reader to know O’Neill—who faded into relative obscurity following his tragic 1992 death from leukemia complications—for the first time in this depth.
