Solomon Islanders Biuku Gasa and Eroni Kumana are portrayed as random natives, when in fact they were dispatched by the coastwatcher Arthur Reginald Evans to find the sailors. The film shows Ensign Ross first suggesting the idea of using a coconut for a message, using a knife to carve it. Gasa later claimed to have suggested the idea and to have sent Kumana to pluck a fresh coconut. The actors playing Gasa and Kumana were not credited, though the senior native is mentioned by name when the large canoe arrives.
