Yeon Sang-ho has directed over ten animated films.
 His second feature The Fake (2013) critiqued organized religion, as a cult leader swindles rural, uneducated villagers out of their compensation money, while no one believes the local wastrel who discovers the truth (the characters were voiced by Oh Jung-se and Yang Ik-june, who previously starred in Love Is Protein and The King of Pigs)
 Inspired by the works of Satoshi Kon and Minoru Furuya, Yeon said the incidents in the film were drawn from his own life, and he cried while writing the screenplay
