The document discusses the locations used for shooting a film preliminary task. The first location was the school corridor by the lockers to introduce the main character standing out against a plain background. The second location was the corridor leading to the stairs to show the character walking toward the next area. The third location used the stairs to clearly show the character following another character and lead viewers to the next floor location. The stairs also prevented confusing viewers about how the characters suddenly reached the top floor. Further locations included opposite sides of the same area for a mugging scene and a central area for a chase scene climax.
