Gautham Karthik in Mani Ratnam's Next ?

The legendary Director Mani Ratnam's recent offering 'Kadal' was a huge let down to his millions of fans. Following the debacle ,Mani Ratnam was reported to have signed in Aamir Khan and Kareena Kapoor for a Bollywood movie titled 'Lajjo'. However things have now taken another U Turn as reports now indicate that Mani is silently working on his next Tamil Movie and Gautham Karthik who made his debut in Kadal will be essaying the lead role again.
Mani Ratnam does have the habit of casting his heroes in subsequent films as he did the same with Arvindswamy who made his debut in Thalapathy and was then cast as the lead role in Roja and then again in Bombay.
