 Critics praised Jung's short "The Killer Behind the Old Man" as the strongest and most stylish entry.In it, a son hires an ultra-methodical hitman (played by Andy Choi) to assassinate his own father, but the killer however finds himself transfixed by the man's slow-moving and ordered life, and thus hesitates to carry through with his mission.Jung was invited to present "The Killer Behind the Old Man" at the 9th London Korean Film Festival in November 2014.
