Leviathan – showing in (a very few) cinemas in London from tomorrow – is a portrait of a commercial fishing trawler, its crew, their haul and the ocean that surrounds them. Made by Harvard’s Sensory Ethnography Laboratory, Leviathan strands its audience at sea, hurls you around and then slowly drowns you – first in fish guts, then in a dark watery abyss. The directors, Lucien Castaing-Taylor and Véréna Paravel, were inspired by Moby-Dick; they read aloud from the novel on deck while filming.
