The British Empire owed a lot to opportunistic soldiers of fortune as well as to explorers: men who risked their lives (and the lives of others) for profit, fame and the recognition from their peers for their accomplishments. In the last category one could think of men like Livingstone, Stanley, Scott and Burton. Captain Richard Francis Burton (whose life we follow in this film) risked a lot for the sake of discovery (to find the source of the Nile) but at the same time he was also a man with a genuine interest and outmost respect for the indigenous peoples and cultures found deep in Africa.
In the film we see Burton joining forces with a young and ambitious Lieutenant (Lt. Speke) to travel again to his beloved Africa to locate the source of Nile with an expedition funded by the Royal Geographical Society. The film is an account of this trip but shows also events before and after this. Watching this movie we can grasp the differences between the two men, their strong ties and friendship during their common effort in the expedition and also later how each one coped with their success at home (London).
The Mountains of the Moon is a fascinating film. It tells a great story without romanticizing the situations during and after the trip to Africa. Burton, Speke and their comrades endured too much to find the source of Nile, and all of them for their own reasons. The novel by William Harrison (that this movie is based on) does not fall into the trap of trying to imitate Conrad's 'Heart of Darkness' but gives us a different perspective altogether. Do not miss this film.
