Unique collaboration between (arguably) the most celebrated director of the late silent era, and its most famous documentary maker. FW Murnau and Robert Flaherty conceived a dramatic narrative which would also be an ethnological depiction of the people of Bora Bora in the South Seas. Flaherty soon left the project because he felt there was too much drama and not enough ethnology.
So Murnau directed solo a story drawn from the indigenous population. It's a silent film, but with an embedded musical soundtrack. He used local people as his cast and crew, assisted by an American cinematographer, who won the Oscar (Floyd Crosby). And he was fortunate to discover two charismatic amateurs to play the leads.
The actors are credited in their character names. Reri is a young girl chosen for the traditional role of a sacred virgin. But she is in love with Matahi. They run away to an island inhabited by the French colonialists, but are pursued by the indigenous elder (Hitu) and the foreign administrators and police who don't want a tribal war.
Many events are photographed at sea because the people survive off the ocean. And Matahi makes a living as a pearl diver when he escapes from his home. It's a tragedy which probes the iniquities of empire and explores a way of life unfamiliar to western audiences. It benefits hugely from being the (final) work of one of the greatest ever film makers.
