I loved this movie as a young boy. It got me interested in history, especially the story of Europe's efforts to discover the geographic source of the mighty Nile River. Spencer Tracey as Stanley and Cedric Hardwicke as Livingstone are superb. Spencer Tracy didn't think much of the quote "Dr Livingstone I presume" and it took many takes for him to get it right. Supposedly he kept laughing when saying the line. Ironically that line helps make the film so memorable. If you enjoyed MOUNTAINS OF THE MOON you will enjoy this old black and white film classic as well.Not everything in it is historically accurate. In the film Stanley vows to return to Africa to follow in Livingstone's footsteps, but instead becomes a brutal exploiter of Africa for the King of Belgium.
