Miloš Vojnović is the documentary’s historical advisor. The film is narrated by Paul Moriarty.

Škundrić produced it through Belgrade-based Paradox Film. Film Center Serbia and the Ministry of Culture and Information of the Republic of Serbia supported the project, whose production took four years, from 2014 up to 2018.
