Sanath and Madonna Sebastian's upcoming romantic film has locked a release window. On the occasion of Christmas, the makers announced that the film will hit theatres during the month of February 2026. An exact date is yet to be revealed by the team. However, it is being speculated that Heartin will hit theatres during Valentine's Day. Helmed by first-time filmmaker Kishore Kumar, Heartin also stars debutant Emaya T in a prominent role.

The film is currently in its post-production stage and Madonna had recently wrapped dubbing for her portions in the movie.

Speaking about the film, director Kishore Kumar had, on an earlier occasion, said, "Heartin is a rom-com with an interesting balance of romance and humour. We are creating a film that will appeal to audiences of all kinds." He further revealed, "In a way, the film is set in a space that deals with two episodes of Sananth’s character’s life—his first and current love."

On the technical team, the film has cinematography handled by Mukes, known for his work in the web series Suzhal and the film Kolaikaaran. Music for this film has been composed by Rajesh Murugesan (Neram, Premam, and Gold) while editing has been taken care by Barath Vikraman (Good Night, Lover).

Heartin has been produced by R Ravindran under the banner of Trident Arts and co-produced by Step One Studios.
