The same year that this film was chosen to compete at the Cannes, the government sent a delegation of Thai film-makers to the festival. Ironically, when the director asked to be included, officials denied him support, saying that there were no more plane tickets.
The film was inspired by the adventure tales of Thai author Noi Intanon and by Jacques Tourneur, director of I Walked With a Zombie and the original Cat People.
The original title in Thai means in English: "Beast" or "Monster". The director translates the original Thai title into English as "Strange Animal". This is the literal, word-for-word translation (Sud = Animal, Pralad = Strange).
Chosen by the French film journal "Cahiers du cinéma" as the best film of 2004.
