Two Africans who appeared in the movie were named in the programme which accompanied its British release in 1925, and were according to the blurb, associated with the real story of Livingstone. Said Bin Abdallah is claimed to have been personal servant to Stanley as a youth, and present at the famous meeting of Stanley & Livingstone. Adam of Kuruman was, as a child, saved by Dr Robert Moffat from slavery.
According to a contemporary programme the expedition to film the African sequences left England on 26 October 1923 and returned on 8 November 1924, the expedition having travelled 25,000 miles. The actresses required for the African portion travelled only part way, and returned on 24 December 1923. As far as possible the expedition followed the route taken by Livingston himself, involving walking for over 1200 miles carrying two "movie" cameras.
M. A. "Duke" Wetherall, the producer, director and actor that played David Livingstone was behind the creation of the infamous "surgeon's photo" of the Loch Ness Monster, proven to be a hoax in the 1990s. His son, Ian Colin Wetherell, who took the actual photo, long believed to be a genuine image of Nessie's head and neck, played Livingstone as a ten year old boy in this movie.
