A significant portion of the footage was taken by the expedition team, while additional images and interviews were added later by the director, including interviews with Reinhold Messner (who called the feat "a unique statement in the history of mountaineering"), and other major high-altitude mountaineers,[1] and Purja's family (including his wife and brothers). The film premiered at the DOC NYC Film Festival, and was released on Netflix on 29 November 2021.
