Shim has been the driving force behind Myung Films, which she originally founded in 1992 as Myung Planning, a film production company that became instrumental in establishing new genres and discovering new talent (Jeon Do-yeon, Song Kang-ho, Choi Min- shik). The company’s filmography includes now classic works like Kim Jee-woon’s The Quiet Family (1998), Kim Ki-duk’s The Isle (2000), and Park Chang-wook’s Joint Security Area (2000). Shim continues to balance both commercial and creative success with recent productions including Boo Ji-young’s Cart (2014) and Im Kwon-taek’s Revivre (2015).
