A more typical use of an image system includes the repetition of a particularly easy to remember image toward the end of a film, signaling to the audience that the story has come full circle and is therefore about to end. Figure 17 shows Dae-su being released from his imprisonment early in the film after a hypnosis session, while figure 18 shows him in the last scene in the film, after he wakes from an-other hypnosis session designed to make him forget the in-cestuous affair he had with his daughter. The composition of both of these shots is purposely unusual and therefore easy to recall by the audience, with both shots employing a high-angle long shot that shows Dae-su staggering on the ground. This particular use of an image system is very popu-lar among filmmakers, even in films that do not incorporate image systems as intricately as Oldboy does.
