“To hold an ice core is to hold the earth’s memories in your hand.” So says Icelandic poet, playwright, author and filmmaker Andri Snær Magnason, the human subject of Fire of Love (2022) director Sara Dosa’s breathtaking documentary. He had the unenviable task of writing funeral rites for the first of Iceland’s world-famous glaciers to melt into stony silence. His grandparents, Hulda and Árni, were intrepid glaciologists, among the first to explore the nation’s icy wealth, even spending their honeymoon on the behemoth Vatnajökull. Magnason shares their incredible archival footage with Oscar-nominee Dosa, amplified by stunning new footage captured by cinematographer Pablo Álvarez-Mesa. As our trusty guide, the poet’s richly sonorous voice draws a glimmering line from glaciers’ integral place in Norse creation myths, through ancient songlines to his children and on to a desolate timeline where humanity’s greed might yet see the annihilation of these majestic titans alongside the chattering puffin colonies that cling to the nation’s cragged cliffs. Far from despairing, this Sundance highlight is a clarion call reminding us all that we have the power to reshape the future, much like the glaciers carve their path through mountains.
