The title in satirical film posters is one of the most important communication elements that, through its visual features, both allows for easy reading and plays an effective role in representing the identity and content of the film. The purpose of examining satirical components is to familiarize oneself with the design methods in the structure of letters and words that are included in the titles of these posters. In line with this goal, the authors seek to answer these questions: 1- What are the written visual components (methods of writing the structure of letters and words) in the design of satirical film poster titles? 2- How does the visual function of the components appropriate to the content of satirical films occur? Accordingly, this research has been formed using a descriptive-analytical method and based on library resources and a targeted statistical population based on sources of satirical posters in Iranian cinema history. The visual components of humor derived from statistical findings that express a specific and diverse tone of writing personality, character of letters and words in the titles of humorous movie posters include: exaggeration, color contrast, contrast of line thickness, special writing, humorous visual elements, visual puns, contrast of visual culture, intensification of positive and negative space, humorous visual effects and improvisation. The components extracted from the research show that these components can not be exclusively specific to the humor genre and cover other cinematic genres such as social drama.
