Filmmakers worldwide have masterfully employed rain, not just as a backdrop, but as a potent narrative device. South Indian cinema, in particular, imbues rain with profound meaning. From the drought-breaking deluge in ‘Vaishali’ to the emotional downpour mirroring characters’ struggles in ‘Perumazhakalam,’ and the romantic showers in Mani Ratnam’s ‘Alaipayuthey’ and ‘Mouna Ragam,’ rain consistently amplifies cinematic storytelling.
