Contrary to Charlatan, Mašek has opted for a different approach to tackle the biopic genre. In the director’s explanation, he notes that Arvéd will be more of “a claustrophobic tragedy about imprisonment” based on chamber dialogues. The situations in the story will bear aspects of an “absurd, Kafkaesque world” featuring grotesqueries, paradoxes and black humour. The director conducted research into how the occult and esoteric societies functioned in Czechoslovakia during the 1930s and 1940s with a historian.
