Here is the trailer for the film ForeBears by Marie CACHET and Varg VIKERNES. It will be available in English (subtitles, the audio is norwegian) on DVD from March 2013 ONLY on Amazon.
To summarize the story, Varg is thinking and discovers bit by bit what happened before. A kind of journey in reverse through time and in thought, to prehistoric time (about 30 000BC), up to a previous life when he was a little boy. Through what he lives again in this little boy, he understands the meaning of certain essential rituals of that prehistoric time, that still have a major influence on modern habits.
