Dulquer Salmaan has previously stated in an interview that Kaantha is not a biopic, but rather a fictitious crime drama largely influenced by Bhagavathar's age and persona.
Production and Technical Details Kaantha has a U/A certificate and runs for around 2 hours and 43 minutes. Dani Sanchez Lopez shot the film, Llewellyn Anthony Gonsalvez edited it, and Jhanu Chanthar composed the music. Ramalingam is in charge of the art direction, while Poojita Tadikonda, Archana Rao, and Harmann Kaur create the outfits.
Advance bookings are currently open in Tamil Nadu, the Telugu states, Kerala, the rest of India, and global markets, indicating the film's high anticipation.
