The Most Unknown
2018, English. Directed by Ian Cheney.
An epic documentary film that sends nine scientists to extraordinary parts of the world to uncover unexpected answers to some of humanity’s biggest questions. How did life begin? What is time? What is consciousness? How much do we really know? By introducing researchers from diverse backgrounds for the first time, then dropping them into new, immersive field work they previously hadn’t tackled, the film pushes the boundaries of how science storytelling is approached. What emerges is a deeply human trip to the foundations of discovery and a powerful reminder that the unanswered questions are the most crucial ones to pose. Directed by Emmy-nominated and Peabody Award-winning filmmaker Ian Cheney and advised by world-renowned filmmaker Werner Herzog, The Most Unknown is an ambitious look at a side of science never before shown on screen.
