Samantha was the initial choice by Vettrimaran for his trilogy Vada Chennai
. Samantha signed the project, as she wanted to do more serious performance oriented roles. But her sudden marriage plans and not to sign any more new movies changed her course and she backed out of the project. At the pooja of the film Dhanush announced that the movie will be a trilogy and Samantha could not give them bulk dates and invest her time for three movies. Now, Wunderbar films owned by Dhanush has approached Amala Paul for the project and Amala has agreed to give the team bulk dates for the film. Dhanush and Amala earlier acted together in the blockbuster Vellaiyilla Pattadhari
. As for Dhanush, he is awaiting his movie Thodari
