Post production on the documentary began ten years after capturing the footage.
The Victorian era story line that appears throughout the documentary is repurposed footage from Yarbrough's first feature film, The Unknowing, shot several years before the documentary. The footage seen in Captivity spans a total of seventeen years.
Yarbrough spent six months editing the project on Adobe Premiere CS6 but suddenly had to finish the film on an old desktop with an old version of IMovie. During the editing process, he chose the order of scenes by adhering to a rotating pattern of the few aspects of himself he was trying to showcase. Philosophical ponders, creative process, maintaining a positive attitude and his naive and idealistic view of the world.
The rap songs appearing in the film are the work of recording artist Freeman Claridge, who was Yarbrough's roommate while attending Texas Tech University. The two estranged friends had no idea they were both living in Los Angeles until the day of the annual Abbott Kinney festival. Yarbrough had gone into a store, Aviator Nation, to escape the large crowd roaming the boulevard. He was sitting next to a lava lamp, when in walked another artist seeking refuge, it was Freeman. They both smiled and exchanged numbers.
