Heartiley Battery trailer and story:
The trailer of Heartiley Battery was released on social media on Monday. The story revolves around Sofia, a brilliant science enthusiast who has always believed that love is nothing more than a mix of biology and chemistry. Having witnessed a lot of broken relationships, including that of her parents, she is all set to remove ambiguity from love. At just 16, she dreams of inventing a device that can scientifically measure love’s authenticity. Years later, at 24, Sofia finally succeeds - only to meet Sid, a comic writer who thinks her invention is absurd.
Guru Lakshma, who plays Sid, said in a statement, “It is a character who believes deeply in emotions, instinct, and the magic of love. Playing him allowed me to explore vulnerability and humour in equal measure. Heartiley Battery is not just a love story; it’s a journey of understanding what the heart truly wants, and I can’t wait for audiences to witness it.”
Padine Kumar said, “Sofia is a character I instantly connected with - driven, brilliant, and someone who believes she can understand love scientifically. But beneath her confidence lies someone afraid of emotional instability. Playing her was both challenging and fulfilling.”
The technical crew of the series includes cinematographer Coolie Sounderrajan, Nizam in charge of editing, VFX and CGI and music director Michael Akash.
