A gothic film that reprises Nadja’s eerie predilection for the undead, The Eternal relates the story of an American couple who journey with their young son to Ireland and encounter a strange relative (Walken) who keeps a two-thousand-year-old corpse in the cellar. As in Kubrick’s The Shining, the child seems more attuned to what is going on than the adults, who are easily baffled by a shape-shifting Druid witch who is transformed into a body-double for the alcoholic wife. Lyrical underwater photography and strong performances (especially Elliott in a dual role) highlight this unusual production.
