Strange, arty horror movie filmed in Devon, England about a mysterious traveller who turns up at the coastal home of John Hurt and Susannah York (who gets her clothes off several times) and claims to have magic Aboriginally powers. Indeed he possess a deadly shout, hence the title. Nicely filmed and compelling, with a great cast but if you can understand the ending then you are more clever than me! Just enjoy for the strangeness and visual pleasure.
