[2] In 2002, he made his narrative feature film debut with Too Young to Die, based on the real-life story of Park Chi-gyu and Lee Sun-ye, a man and woman who fell in love in their early seventies then rediscovered sex.
[12] Park continued to blend reality and fiction in Voice of a Murderer (2007), based on an actual 1991 kidnapping case of a young boy whose distraught parents (played by Sul Kyung-gu and Kim Nam-joo) receive threatening phone calls for 41 days.
[13] The boy's parents granted Park permission to make the film, with which he hoped to advocate extending the statute of limitations for child abduction-murders to longer than the current 15 years.
"[14] Closer to Heaven, another unconventional romance between a man with Lou Gehrig's disease and his funeral director wife, also became a commercial success in 2009 and garnered acting awards for Kim Myung-min and Ha Ji-won.
[15][16] In a marked change from his previous work, Park's Love Forecast (2015) was a romantic comedy about a feisty weather reporter and her best friend of 18 years, a mild-mannered elementary school teacher (played by Moon Chae-won and Lee Seung-gi).
