In 2014, Jung along with Chinese actors Francis Ng and Chang Chen, directed three short films for "Three Charmed Lives", an omnibus commissioned by the Hong Kong International Film Festival. 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.
