The effect of Sadako coming out of the well was accomplished with only one simple special effect. The actress who played Sadako, Rie Ino’o—who was a student of the Kabuki theatre, which uses exaggerated motion and jerking movements to emphasize emotion—was heavily involved in the development of the Sadako character. Ino’o was filmed walking backward and the film was run in reverse. The end result is Sadako walking forward with unnatural motions.
