The filmmaker was found dead in his hotel room in Poland on Friday (18Sep15). Police are currently investigating the circumstances surrounding his death.

A statement from Wrona's publicist, Jim Dobson, reads: "Marcin was a personal friend of mine and we are quite devastated at the news but his family wanted to me to announce his passing."

At the time of his death, Wrona was preparing to debut his film Demon at the Gdynia Film Festival in Poland.

A representative for the festival says, "We would like to express our sincere condolences to the wife of the director and all the people who were close to him."

The film made its worldwide premiere to rave reviews at the Toronto Film Festival in Canada last week (13Sep15), and is slated to hit theatres in October (15).

During his career, the filmmaker was feted with the Student Film Award at the Tribeca Film Festival in 2002 for Magnet Man, and his first feature film in 2009, My Flesh My Blood, won the Journalist's Award and The Best Script Award at the Polish Debuts Film Festival.

He also worked in TV on projects like The Parasite, The Flaw and Ratownicy.
