Maniratnam seems to be increasing his speed after tasting success with ‘OK Kanmani’. According to the latest it is coming out that he will be directing Karthi in his next and shooting will start from September. A source reveals, “Karthi has been confirmed for Mani Ratnam’s film but he is yet to sign on the dotted line. Karthi and Mani Ratnam met recently and they have discussed about the film. Talks about the project are in the initial stages as nothing — including the genre of the film has been finalised. Right now, Mani and Karthi will be working together and the shoot has been planned during the month of September.” Karthi worked with Maniratnam as assistant director for his film ‘Aayutha Ezhuthu’, before making his debut as hero with ‘Paruthiveeran’. Karthi is starring in Nagarjuna’s multi starrer titled ‘Dosth’ under Vamsi Paidipally’s direction.
