This qualitative study investigates the functional realization of illocutionary acts by secondary characters in the animated film Luck, focusing on pragmalinguistic patterns in their dialogue. The researchers identified relevant characters by analyzing user-generated viewer comments, then extracted and segmented their scripted utterances for pragmatic analysis. The study aims to deepen theoretical understanding of illocutionary acts in non-central characters—an underexplored area in speech act research—and to offer new insights into character construction through language. The researchers applied Searle’s (1976) taxonomy of illocutionary acts and operationalized the analysis using Miles, Huberman, and Saldaña’s (2014) interactive model of data condensation, display, and conclusion drawing. They analyzed the illocutionary functions of Sam and Bob in relation to their narrative roles and interpersonal strategies within the film’s discourse. The analysis identified four categories of illocutionary acts that serve specific character-building functions. Sam predominantly used expressive and directive acts, highlighting her desire to escape the misfortune that shapes her identity. In contrast, Bob consistently used assertive acts, conveying information and opinions with clarity and confidence. Theoretically, the study enhances our understanding of how illocutionary acts shape character identity in animated narratives, a domain where pragmatic functions often receive limited attention. Practically, the findings provide valuable input for English educators and learners by illustrating the real-world application of speech acts in emotionally nuanced contexts.
