The elegant, humorous, susurrating Welsh voice of Siân Phillips sets the keynote for this whimsical essay documentary from Belgian film-maker Sofie Benoot about the nature of rock and stone, and the mysterious interrelation between our bodies and the landmass of Earth.
Benoot’s starting point is the kidney stone that has just been removed from her body, an intriguingly smooth and worn pebble; it’s a personal event she assigns to her offscreen alter ego, voiced by Phillips. This quasi-fictional narrator musingly notes that once upon a time she provided the voice for nature documentaries; quite true, Phillips has indeed narrated some nature documentaries, which appears to be the reason why Benoot cast her.
