I-San Special (Thai: คืนพระจันทร์เต็มดวง, or Kuen pra chan tem doueng, literally Night of the Full Moon) is a 2002 Thai experimental independent drama film directed by Mingmongkol Sonakul and based on an idea by Apichatpong Weerasethakul. Set aboard a ramshackle inter-city bus traveling from Bangkok to Isan, the audio of a Thai radio soap opera is acted out by the passengers. However, when the bus stops, the drama of the passengers' normal lives is portrayed. Parallels are seen between the soap opera and reality in terms of the characters' social class.
