To aid in realistically portraying talking individuals, Square developed a technique called Facial Motion. By capturing the facial movements of real world actors, Square could program such movements into the characters. Anyone who has seen movies of the game in action can attest to the fact that Squaresoft has been quite successful. In some scenes, Tidus and Yuna purse their lips, furrow their brows and reproduce other such mannerisms while speaking that is so realistic that it creates the illusion that they are in fact real people.
