Symbolism plays a major role in the visual storytelling, with the constant motion of the train mirroring the protagonist’s unsettled mind. Reflections in windows and mirrors further emphasize her fractured perspective. Every visual detail, from pacing to framing, contributes to the audience’s sense of immersion and connection with the unfolding drama.

📚 Comparison with the Novel
The movie remains faithful to the central themes of Paula Hawkins’ bestselling novel but makes certain adjustments for cinematic pacing. Key events are streamlined, and some side characters receive reduced screen time to keep the narrative focused on the main mystery. This adaptation choice ensures the suspense remains high while still honoring the spirit of the source material.
However, the shift from page to screen naturally alters how internal thoughts are presented. Where the novel relied on the protagonist’s inner monologue, the film uses visual cues, body language, and symbolic imagery to convey emotional states. This change offers a more immersive experience for viewers, though some novel purists may miss the intricate psychological detail of the book.

The choice of filming locations enhances the feeling of both intimacy and detachment. Audiences get glimpses into private lives from a distance, reflecting the theme of partial truths and limited perspectives.
