Among the unknown worlds in the universe, we can count our very own bodies. Like planet earth, each of us is made up of fascinating landscapes that are home to all kinds of wildlife.
The film takes the viewer on a unique microscopic safari, where we encounter some of the myriad creatures that live, thrive, compete, feed, are born and die on or inside our bodies. In fact, microscopic creatures play a more powerful role than we know: These life forms impact our health, our life expectancy, our physique and even our behavior.
The film renders these hidden worlds visible with the help of special effects: Combining cinematic electron microscopy with a super macro film technique. The documentary explains cutting-edge scientific findings, by turns surprising, enlightening and amazing. It raises questions about who we are, and how we exist in the unexplored, complex ecosystems that help constitute us.
We are born 100% human, but will die 90% microbial. Between these two points in our lives lies the unexplored terrain of ‘Life on Us’.
