As a boy, the Viking prince Amleth bore witness to the slaying of his father Aurvandill (Ethan Hawke) by his treacherous uncle Fjlnir (Claes Bang), who’d desired his mother Gudrn (Nicole Kidman). Having fled for his life, he swore he’d have vengeance-and the day came that Amleth (Alexander Skarsgrd), grown into a formidable barbarian, returned to claim it. Robert Eggers’ brooding, brutal take on the mythos that inspired “Hamlet” co-stars Anya Taylor-Joy, Willem Defoe, Bjrk. 136 min. Widescreen; Soundtrack: English.
