2013 film by Aleksei Yuryevich German
Hard to Be a God (Russian: Трудно быть богом, romanized: Trudno byt' bogom) is a 2013 Russian epic medieval science fiction film directed by Aleksei German who co-wrote the screenplay with Svetlana Karmalita. It was his last film and it is based on the 1964 novel of the same name by Arkady and Boris Strugatsky.
A team of scientists travels from Earth to the planet Arkanar, which is inhabited by a race of humans identical to those of Earth. Their civilization has not progressed beyond a civilization that is culturally and technologically nearly identical to medieval Europe. One reason may be the militantly anti-intellectual attitude of Arkanar: Anyone whom the inhabitants of the planet consider to be an "intellectual" is instantly executed. The Earth scientists are ordered not to interfere and to conceal their identities; but one of them, Rumata, wishes to stop the senseless murders of brilliant minds and is forced at last to pick a side.
