Abstract :
The research entitled ?An Interactive Meaning on the Harry Potter Movie Posters? focuses on the application of interactive meaning and systemic functional linguistics in describing the interactive aspects of the Harry Potter movie posters. By using the basic qualitative descriptive method implemented on data in the form of eight Harry Potter film posters, the researcher has two objectives, that is (1) to discover the interactive meaning of the Harry Potter movie posters; (2) to find out the text meta-function of the Harry Potter movie posters. The result of the study shows that there is a tendency to display an offer image (87.5%), far social distance (37.5%), frontal angle (87.5%), a balance between elements showing power and vertical angle, and an inclination to display naturalistic modality. For the text meta-function, there is a Material Process (87.5%) which is delivered through a declarative clause (100%) with the aim of declaring a statement to the viewer (100%). In conclusion, Harry Potter movie poster applies the use of interactive meaning and systemic functional linguistic aspects in constructing a sustainable meaning and message conveyed through the actors displayed (represented participant) to the viewers (interactive participant).
