This study investigates the symbolic imagery embedded in the 2007 animated fantasy movie Beowulf, directed by Robert Zemeckis, as a modern reinterpretation of the earliest known English epic. The original poem, composed in Old English and believed to have been transcribed by a Christian monk around the 10th century, reflects both pagan Scandinavian myth and the Christian worldview of its time. The film adaptation, utilizing motion capture technology to enhance its mythical and visual expressiveness, provides a rich landscape for symbolic interpretation. This research explores how key images—the monster Grendel, the dragon, and the golden treasure—function not only as narrative tools, but as metaphors for existential themes such as heroism, corruption, fear, and mortality. The dragon represents the destructive force of pride and greed; Grendel embodies the psychological and social concept of the monstrous “Other”; and gold symbolizes both wealth and decay. The study also examines how the Christian moral undertones subtly woven into the original text are translated or reimagined through cinematic language. Special attention is given to the film’s portrayal of Grendel’s suffering in contrast to the warriors’ joy, suggesting a deeper reflection on human alienation and moral duality. By combining a semiotic approach with mythological analysis, the paper reveals that Beowulf functions not only as a digital spectacle, but as a critical reflection of early medieval values and modern anxieties. Ultimately, this study argues that the symbolic imagery in Beowulf offers insight into the transformation of heroic ideals and the reinterpretation of myth in a contemporary cultural context.
