The purpose and problem of this thesis is to formulate a theory on screenplay aesthetics with Eisenstein's montage as the mother theory providing the aesthetic nourishment for the proposed concept of imaging. The theory of screenplay imaging proposes that the screenplay is a montage of sub-narratives occurring in the sensual, emotional, and intellectual dimensions and expressing the grand narrative theme. It further suggests that the interaction between the screenplay and the reader-interpreter should yield a prolificity of interpretation with a unified meaning. The thesis consists of five chapters. Chapter I, Introduction, lays the background for subsequent arguments. Chapter II, The Principles of Montage, discusses Eisenstein's theory. Chapter III, The Theory of Imaging, explains imaging and develops Gonzalez's Model of Imaging. Chapter IV, The Principles of Sensual, Emotional, and Intellectual Imaging, explains the three dimensions with examples. Chapter V, Conclusion and Recommendation, suggests improvements and applications of the theory.
