After learning about Robertson’s incredible story, Faunce convinced Jorgensen to produce a documentary about the missing soldier. In 2012, he began working on Unclaimed, which follows Faunce as he tracks down the man who claimed to be the long-lost Special Forces Green Beret. While initially skeptical, Faunce becomes convinced about the man’s identity as he spends more time with him.
In the documentary, Robertson opens up about his time in the military and his life after the war. Speaking only in Vietnamese throughout the film, he talks about how he was captured by Viet Cong forces after the crash and how he was starved, tortured, and kept in a cage.
