Another single from the upcoming Tamil film Harkara, Kaali vs Graamam, was released by the makers on social media recently.

The song features actor Kaali Venkat as a postman, as he goes about doing his day's job, while also facing some practical difficulties and conversing with the villagers he is serving for. The song is voiced by Ramshanker and N Pavithraa, with lyrics by Deepak Krishna. The music is scored by Ramshanker.

Harkara is directed by Ram Arun Castro, who will also be starring in the film. In a previous conversation with CE, Ram had said that the film will be a historical drama with comedy element. "The story will run in two periods, 1870s and 2023. While I will act as the postman in the period portions, Kaali Venkat will represent the present timeline. The story will be about the postal service from the times of the first postman to the current," he had said.

The technical crew of the film consists of two cinematographers, Philip R Sundar and Lokesh Elangovan, who shot the past and present respectively. Dani Charles is the editor. The makers are yet to announce a release date.
