One of the biggest films in production right now, Mani Ratnam’s Chekka Chivantha Vaanam is not only massive in terms of its casting, but also in its scope.

Jointly being produced under the Madras Talkies and Lyca Productions banners with music by A. R. Rahman, the first schedule of Chekka Chivantha Vaanam also being made as a bilingual in Telugu under the title of Nawab had canned few key portions on ECR as well as at the Apollo Hospitals at Vanagaram.

With an enormous range of acting talents in the film, actor Simbu is perhaps the most popular star at present in the production.

That said, there have been rumors of late surrounding STR’s role in Chekka Chivantha Vaanam with a few stating he is playing an engineer in the film.

Meanwhile, it has now been confirmed Simbu is not playing an engineer in the film as being reported.

It has been further stated STR is working hard to shed more weight and tone his physique to nail the fit look as similar to his Poda Podi days.

It must be noted Simbu had previously portrayed the role of an engineer in the 2010 blockbuster, Vinnaithaandi Varuvaayaa.

It looks like we will now have to wait a while longer to know the role STR is playing in Chekka Chivantha Vaanam.

As for the rest of the cast in the film, actor Jyothika will be seen after her powerful performance in director Bala’s Naachiyaar.

Amidst the several acting projects, Vijay Sethupathi lovingly called 'Makkal Selvan' by his fans has taken up yet another role with this film.

Arvind Swami’s career has taken a new course post his Thani Oruvan in 2015 and is collaborating with Mani Ratnam once again after Kadal in 2013.

Aishwarya Rajesh has bagged yet another biggie this year after Vikram’s Dhruva Natchathiram and Dhanush’s Vada Chennai.

Post his power-packed performance in Yennai Arindhaal, Arun Vijay showed consistency in last year’s Kuttram 23 and he has joined the Chekka Chivantha Vaanam cast today to begin filming his portions.

Aditi Rao Hydari left a spell on Tamil film audiences after starring in Kaatru Veliyidai last year and she is yet another big addition to Ratnam’s ongoing project.

The mystery surrounding each of the stars' roles in the film continue to intrigue us, which we hope will be revealed in the days ahead.
