Interpersonal Functional Mood Analysis of the Dialogue in the Film Dead Poets Society

The Dead Poets Society is an excellent educational film with thought-provoking cultural connotation and a story ending that looks like a tragedy but actually a comedy. The film adopts a multi-thread narrative structure to show the theme, and criticizes the phenomenon that the rigid educational system imprisons the idea. The systemic functional theory of functional linguistics holds that the po-tential meaning of a text can be analyzed through the mood system. Based on the inter-personal function theory of systemic functional grammar, through the in-terper-sonal function mood analysis of the dialogue of the characters in the film Dead Poets Society, this paper reveals the role of the mood function in helping to ana-lyze the relationship between the characters in the work and the meaning level that the film is intended to convey.
