As we all know actor Karthi is presently busy shooting for ace director Mani Ratnam's 'Kaatru Veliyidai'. The versatile actor sports a toned physique and clean-shaven look for the character he plays in the romance flick.

To be produced by Dil Raju in Telugu, the film is said to be titled as 'Duet' in Telugu. "Pleased to announce our association with Madras Talkies to present," the ace producer has announced a while ago. Like 'OK Bangaram', 'Duet' is quite a trendy title.

Karthi himself has confirmed that the film will be releasing in March 2017.

Aditi Rao Hyadari is playing a doctor. RJ Balaji, Delhi Ganesh and many others are playing supporting characters. Oscar winner AR Rahman is the music director while Ravi Varman works behind the lends.
