"The script is locked for Dhanush-Vetrimaaran project. The technical team is finalised and pre-production work will start in full swing," said producer Dhayanidhi in one of his tweets.
They will make a detailed announcement soon, he said and added that the project has materialised after "three-year" long wait. "We are finally here and it's time to lock and load," he further posted.
Dhanush and Vetrimaaran were last seen together in Tamil romantic-drama Aadukalam, a story about rooster fights in Tamil Nadu.
The film won six National Awards for Best Director, Best Screenplay, Best Actor, Best Editing, Best Choreography and a Special Jury Award.
Their first outing was Tamil romantic-thriller Polladhavan, about a lost bike and its repercussions. It was later remade in Telugu as Kuradu with Varun Sandesh in the lead.
Vetrimaaran has directed two films so far and both of them have been with Dhanush. He produced and penned the story of two recent Tamil films Udhayam and Naan Rajavaga Pogiren.
Meanwhile, Dhanush is awaiting the release of Hindi debut Raanjhnaa and Tamil romantic-drama Mariyaan. He is currently shooting for Tamil comedy Naiyaandi.
