The Most Unknown is a 2018 documentary film, directed by Ian Cheney, that introduces nine researchers from diverse scientific backgrounds to areas of scientific field work new to them. The film has had mixed reviews, with some reviewers focussed on the participants' contagious fascination with research on life's biggest mysteries ("the most unknown"), while other reviewers criticised the film's coverage of difficult technical concepts as lacking depth.
Description
The film presents interviews with nine scientists, each conducted by a scientist in another discipline—"a geobiologist, molecular biologist, various physicists studying space and time, cognitive psychologists, and a neuroscientist—who take turns visiting one another to get a cursory taste of the other's field", according to The Village Voice. Film Journal International said, "In each of the nine segments, one scientist travels to meet another scientist of a different discipline to learn about the research they're doing. Then the scientist whose research has just been discussed heads off to a new location (usually remote, always beautifully lensed) where somebody from a separate school of study tells them about what they're up to. And so on."

Reviewers described the interviews variously as "a La Ronde of intellectuals", "nine scientists... who visit one another blind-date style", "a round-robin of wonder", "a daisy chain of nine curious scientific minds... a scientific game of tag", "global game of tag with experts", "beads on a chain of discovery", "a daisy chain of one-on-one interviews / lab tours", "an intellectual relay race or high-IQ speed dating", and "a global relay of encounters in an effort to find commonality of language and purpose as life's big questions are explored".

Cast and crew
Scientists who interviewed each other included microbiologist Jennifer Macalady, physicist Davide D'Angelo, psychologist Axel Cleeremans, astrobiologist Luke McKay, astrophysicist Rachel Smith, geobiologist Victoria Orphan, physicist Jun Ye, neuroscientist Anil Seth, and cognitive psychologist Laurie R. Santos.

The documentary was directed by Ian Cheney, with advisor Werner Herzog, and was supported by a grant from Science Sandbox, a Simons Foundation initiative "dedicated to engaging everyone with the process of science".
Distribution
Motherboard Tech by Vice Media used a "multimodal release strategy", premiering the film at the Copenhagen International Film Festival on March 16, 2018; it was released in theaters on May 18, 2018. In the summer it began streaming on Netflix, which had global rights and made it available in 25 languages. Finally it was posted as nine individual episodes on YouTube.
Critical response
Daphne Howland of The Village Voice praised the concept of the film as raising "some of the grandest, if also the most basic, mysteries — like our perception of time or whether there's life on other planets". Howland also commented on the film's beautiful settings as "photogenic", criticizing that the science was not "deeply explained". Ken Jaworowski's The New York Times review agreed, saying the documentary "extols the wonders of science and of all that's yet to discover", but a drawback is that with 10 minute episodes, it is difficult to grasp the concepts, and the scientists are less skilled as interviewers.
Jaworowski said the film "works best as inspiration to delve deeper into these disciplines, and as a celebration of science". The New Yorker's Sara Larson said director Cheney's "goal isn't so much to inform as to inspire, and it's vicariously exciting to watch his subjects step out of their own research and into that of their peers."
Film Journal International said,
Robert Abele of the Los Angeles Times identifies two disarming motifs expressed in the film: "a thirst for knowledge and a belief that there's so much more to learn about what makes us and our world", and "The collegial awe that accompanies a proud nerd's introduction to another's elaborate measuring machines".
