Dhanush and Vettrimaran come together after the success of Polladhavan and Aadukalam, which was critically acclaimed and commercially declared a hit.
This would be the first time in Tamil film industry, where a gangster film will release as a trilogy.
Vada Chennai has a promising cast including Daniel Balaji, Aishwarya Rajesh, Andrea Jeremiah, Samuthirakani among others. Music for the movie is by Santosh Narayanan.
Most of the first part was shot in an elaborate jail set that was erected in Chennai on a lavish budget.
Dhanush earlier last month has tweeted, '#VadaChennai part 1 trailer will be launched on 28th July & the movie will be a September release.'
