A photo of director Atlee from the shooting spot of Mersal was spotted on the social media some time back. Atlee was seen with a family, but that is not what this news is all about. If you zoom the photo and check the posters in the backdrop, you can see Vijay posing in front of a podium with multiple flags at the backdrop.
The poster suggests Vijay is giving a speech and comedian Motta Rajendran is also seen in the same poster. Looks like Thalapathy Vijay might play a role of a politician in Mersal or it might just end as our imagination, but we will have to wait for some more time to know if it is true.
