Multimedia performance "The Dark Man" is the Ph.D. at the University of Arts in Belgrade, which presents the result of many years of research and work on performance and multimedia art. Through different artistic media expressions, the project represents the internal man's process of creating guilty conscience. Using Yesenin's poem and Kubrick's multi-layered cinematic poetics, the project is set as a spatial installation that creates a collage of audience interaction, live performance, and multimedia visual experience. Besides the poetic ideas, the visual, auditory, physical, and performing aesthetics, the project also examines the totality of media expression, both live and recorded, and its relation and action in one artistic unit. The working process on the project resulted in the multimedia installation "Cube," a conceptual pillar of the multimedia performance "The Dark Man." Due to its multimedia nature, the project is divided into video production, design and construction of space installation, sound production, digital animation, work with the actor, and stage setting of the whole project. Pre-production of the project began in September 2013. The "The Dark Man" video material was filmed in a studio, "BP" Zemun, Serbia. Editing and post-production video was made in the "Stankovic and Sons" production house, Belgrade. The first performance took place at Airport City on 24 April 2015 in Belgrade.
