Song Kang-ho is a South Korean actor. Song made his film debut in The Day a Pig Fell into the Well (1996), and came to national prominence with a series of critically acclaimed performances, including No. 3 (1997), Joint Security Area (2000), Sympathy for Mr. Vengeance (2002), Memories of Murder (2003), The Host (2006), Snowpiercer (2013), The Attorney (2013), and A Taxi Driver (2017).

Joint Security Area is a 2000 South Korean mystery thriller film directed and co-written by Park Chan-wook and based on the novel DMZ by Park Sang-yeon. It is Park Chan-wook's third film as director; as he largely disowned his first two films The Moon Is... the Sun's Dream (1992) and Trio (1997), Joint Security Area is frequently regarded as his first film with creative control, and Park himself prefers the film to be regarded as his directorial debut.
