His work has been screened in diverse venues internationally, and received several awards. In 2008 he directed the documentary film " The World of Vija Vetra", an award-winning portrait of the renowned dancer and choreographer, which received the Silver ACE Award at the Las Vegas Film Festival in 2010. This film is also included in the library of the Documentary Edge Resource Center Auckland, NZ, and was screened at the Asheville Film Festival (2009), Harvard Independent Film Group (2008), and Docufest Atlanta (2008). His short film "Journey" screened at Big Apple Film Festival New York (2012). His short film “Room” received the award for Outstanding Conceptual Piece at New School University in 2004 and screened on several venues, including Anthology Archives in New York City (2004), Barcelona International Film Festival (2005), and Flickering @ Cornerstone Festival (2004). Kostic also worked as producer and cinematographer for the 2014 Vladan Nikolic film "Allure", which was selected to premiere at PÖFF |Tallinn Black Nights Film Festival in 2014.
Kostic has also produced a variety of video art installations, including "Storefront Diva" in 2011 and "Digital Debussy", a multimedia theater piece which was presented at The Flea Theater in Tribeca in 2013. His experimental film “Persistence of Memory” premiered at the MaerzMusik festival in Berlin, Germany in March 2012 in conjunction with Joan La Barbara's concert work of the same name. The theme of the festival was “Cage and Consequences” celebrating the 100th anniversary of John Cage’s birth. Most recently, Kostic directed the experimental performance "Parallel Dreams", which was supported by a grant from the Lower Manhattan Cultural Council and selected to be presented as part of Figment Festival 2014 at Governor's Island. In conjunction with this work, he produced an award winning experimental short film "Parallel Dreams" in 2015, which developed over the process of producing this live performance.
As a storyteller, much of his creative work has revolved around the exploration of sense, memory and our movement through life, and understanding how we touch - and are touched by - the larger world we pass through. These themes pervade his experimental short films, “Walk of Life”, “Room”, "A Tomb For Boris Davidovich ", “Journey” and "Parallel Dreams". More recently, he has begun to examine the impact of the unprecedented infiltration of technology into our daily lives, and the extent to which it may be undermining our capacity to perceive and interact with the world and people around us. This idea of technologically-induced isolation and its consequences is the subject of latest narrative project, a feature film entitled "Capio". Currently in pre-production,"Capio" is a science-fiction thriller and a social commentary, about a mysterious entity who uses the hunger for technologically-enabled escape to enslave a city that is more than willing to submit.
Film as dream, film as music. No art passes our conscience in the way film does,
and goes directly to our feelings, deep down into the dark rooms of our souls.
