This storyboard information, was for setting up the confrontation scenes between Mike (Tommy Kirk) and Fred (Beau Bridges).

This setup like the scene with Rick, also mentions the use of miniature street and building items, which were not used in the final scene in the film. The setup of the scene here looks to be quite complex, and most likely explains why most of the giant scenes at the end were shot with the camera angled up to save on the scene complexity.

However, it's not like the complex cinematography wasn't used. Much of what is being written on this page, was used in one long shot where Mike and Fred are sparring in front of the town's courthouse.
