The body of a man, found in the Otztal Alps was found to be over 4000 years old, and the movie has an imagining of his life, and his death.
From the description of the film:
The Ötztal Alps, more than 5,300 years ago. A Neolithic clan has settled nearby a creek. It is their leader Kelab s responsibility to be the keeper of the group's holy shrine Tineka. While Kelab is hunting, the settlement is attacked. The members of the tribe are brutally murdered, amongst them Kelab's wife and son, only one newborn survives... and Tineka is gone. Blinded by pain and fury, Kelab is out for one thing alone: vengeance. He sets out after the murderers on what turns into a grand odyssey where he must fight constantly for the infant s survival; against the immense forces of nature; against hunters he encounters; and, amongst the loneliness of the quest, against a growing sense of doubt over the morality of his mission.
Inspired by the discovery of Ötzi The Iceman , the oldest known human mummy, found in 1991 approximately 5,300 years after his death, ICEMAN is an epic, riveting, visually stunning and immersive revenge thriller that investigates a five-thousand-year-old murder mystery.
NB: the characters in ICEMAN speak an early version of the Rhaetic language. The film intentionally has no subtitles as translation is not required to comprehend the story.
I have a copy of the film on BluRay, and it's on my list of films to view this summer. I shall post a review in due course.
