We had earlier reported that Dhanush will be teaming up with director Karthick Naren for an upcoming film. Tentatively referred to as D43, this project is bankrolled by Sathyajyothi Films. The latest is that popular lyricist Vivek has been roped in to write the film, and will be credited for additional screenplay and dialogues. 

This will be Vivek's first writing credit for a direct Tamil film. He earlier wrote the dialogues for the Tamil version of Frozen 2.

Notably, D43 already has writers Sharfu and Suhas, who wrote the Malayalam hit film Virus, on board the project. 

The film will have Malavika Mohanan playing the female lead, with music by GV Prakash Kumar.
