"Both Simbu and Nayantara worked as true professionals, leaving behind their past and not letting their emotions come in between work. They were cordial to each other while working and maintained a professional relationship off the sets as well," Pandiraj told IANS.
The director wanted the right chemistry between the actors for the love story.
"This is a love story and it's very important for the right chemistry to be produced by the actors. Initially I was a little hesitant but after seeing them work together, my worries subsided. We have completed the first schedule on time," he added.
Nayantara and Simbu had previously worked together in 2006 Tamil romantic-thriller Vallavan. It was after the release of this film they parted ways.
While Simbu is also currently shooting for a Tamil project with Gautham Vasudev Menon and awaiting the release of Tamil actioner Vaalu, Nayanthara is waiting for the release of southern remake of Kahaani titled Anaamika.
