The Eleven Powers: The Festival of Eka Dasa Rudra (1979) Online

As one of the most astounding, larger than life-documentaries of all time, Eleven Powers tells the tale of the last Eka Dasa Rudra festival. The event takes place only every 100 years in Bali, with the last one held in 1979. And if this film crew had not been there to document it, the trials of that calamitous celebration would hardly be believed.

The film shows how the fanatical locals goes about sacrificing at least one of every living thing on the island, into a bubbling volcano, to prevent the destruction of the entire cosmos. Giving a good depiction of frenzied religion at its most savage and insane, while at the same showing such empathy towards the practitioners you somehow start cheering for their rituals to succeed.

The brilliant and brooding narration by legendary Orson Wells, makes it a true gem, not to be missed. However, as the film is apparently only available on a very limited amount of 8mm rolls in certain libraries around the world, digging up a copy can be quite the task.

EDIT: This film is currently available in its entirety on youtube =)
