For Bajrangi Bhaijaan , the "Mmsub" tag is crucial because the film hinges on a linguistic barrier. The plot revolves around Pawan (Salman Khan), a devout Hanuman devotee, who cannot speak Urdu or understand the dialect of a lost mute girl from Pakistan. The irony is poetic: a film about a language barrier requires perfect subtitles for the audience to understand the nuances.
