Suriya's Thaana Serndha Kootam seems to be getting bigger by the day. The film, which already boasts a huge cast, including veteran actor Karthik, Keerthy Suresh, Ramya Krishnan, Nandha and Kalaiyarasan, now has Meera Mithun as its latest addition.

The model-turned-actor, who was a part of 8 Thottakkal, is said to have an important role in the Suriya-starrer. However, the makers are keeping mum about the film and her role in order to maintain suspense.

With music by Anirudh, two singles, Naana Thaana and Sodakku, have already been released. The Vignesh Shivn directorial is expected to hit the screens in January, on the eve of Pongal.
