Shin Sang-ok
Only filmmakers who had previously produced "ideologically sound" films and who were considered to be loyal to the government were allowed to release new films. Members of the film industry who tried to bypass censorship laws were blacklisted and sometimes imprisoned. One such blacklisted filmmaker, the prolific director Shin Sang-ok, was kidnapped by the North Korean government in 1978 after the South Korean government revoked his film-making license in 1975.
