EXCLUSIVE: Iceland, according to legend, was given its name by Norse explorers who encountered the country’s frozen landscape more than a millennia ago. But with climate change melting its glaciers, what is to become of Iceland’s identity? What is to become of the planet as a whole? These are among the urgent themes of Time and Water , the new documentary from Oscar nominee Sara Dosa ( Fire of Love ). Her film is inspired by the book On Time and Water by celebrated Icelandic author Andri Snær Magnason , who serves as narrator of the film.
