Oscar-winning Parasite director Bong Joon-ho and other artists in South Korea have called for a thorough investigation into the death of popular actor Lee Sun-kyun, who played the head of a wealthy family in the class satire movie.

Lee, 48, was found dead in his car on December 27 in what is widely seen as a suicide following an intense weeks-long police probe into his alleged drug use.
