The central conflict of Thattathin Marayathu is the religious divide between the lovers. The film uses the "veil" (the thattam ) as a central motif. Subtitling plays a crucial role in explaining cultural signifiers that might be foreign to a global audience. When characters discuss the nuances of the Muslim community in Thalassery, or the specific festivals and traditions of the Hindu community, the subtitles provide necessary exposition without breaking the flow of the film.
