All blood seen in this short film is real and comes from either director Mykola Yeriomin or an accidentally filmed freak accident when someone cut himself with a metal table in the dorm where he was living.
Filmed in approximately 23 days through the span of eight years (2010-2018) not counting some shots which date back further to 2007.
The project grew as a continuation of several canceled ones including a partially filmed music video, a few webisodes and several deleted scenes from previous productions. The narrative seen was mostly inspired by dreams director Mykola Yeriomin had and music video Kasabian: Vlad the Impaler (2009).
Apart from channeling giallo, slasher, psycho-noir and body horror genres, the movie is made in a self-proclaimed genre of "unexpolitation", a subgenre of exploitation film which succeeds because it never fully explains the events of the movie, although director Mykola Yeriomin only refuses to explain who exactly titular master is and what process of depicted is exactly his or her "return".
Mykola Yeriomin: [Askold Tutylopydirskiy] sticker on the evidence bag suggests that the evidence was recovered by A. Tutylopydirskiy.
Mykola Yeriomin: [multilinguality] The title is in two languages: Italian and English, the latter is used throughout the movie (mostly for credits and significant props), but there are also some lines and signs in Ukrainian and Russian.
Mykola Yeriomin: [actors in multiple roles] Leonid Syplyi portrays both plainclothes cop aiding the Lieutenant, as well as bodybuilder in the post-credits sequence.
Mykola Yeriomin: [dreams] not so much as plot device but as an inspiration for storytelling and editing.
