Poland's film authorities say director Marcin Wrona, whose horror movie "Demon" made its world premiere last week in Toronto, has died unexpectedly at age 42.
The director of Poland's Film Festival, Michal Oleszczyk, said Saturday that Wrona "died suddenly Friday night." He asked for no speculation over Wrona's death until the police investigation is complete.
Wrona was attending the festival in the Baltic city of Gdynia, where his latest movie had its Polish premiere.
A police spokesman in Gdynia, Michal Rusak, said police found the body of a 42-year-old man, whom he did not identify, at a hotel in Gdynia. The police were notified by the victim's wife at 5.30 a.m. local time.
The film authorities expressed great regret over the death of one of Poland's most talented filmmakers.
