Hard to be a God (Aleksei German, 2013). This Russian medieval sci-fi epic is a distant cousin of sorts to Tarkovsky’s Stalker and Andrei Rublev: it shares an author with the former and a sense of grimy, lived-in medieval authenticity with the latter. But the excess and even derangement of Chimes at Midnight is here too. The planet Arkanar is a world of dirt, blood, spit, fog and gore and your engagement is less about a coherent plot than an immersive experience that has the consistency, or even pungency and texture, of a nightmare. Rain means something in Tarkovsky, but here it is just rain. It is constant and it turns everything into mud.
