	Kukrit Pramoj, a Thai politician and scholar, was hired as a cultural expert/advisor to the film and later played the role of Sarkhan's Prime Minister "Kwen Sai". Later on, in 1975, he, in fact, became the 13th Prime Minister of Thailand. Probably because of this, the word "Sarkhan" entered the Thai language as a nickname of Thailand itself, often with a slight self-deprecating or mocking tone. Much of the 'Sarkhanese' spoken in the film is actually Thai.
