Though it is for sure that Rajesh would direct a dual hero subject starring Arya and Jiiva in the lead roles, the project will not take off immediately, thanks to a commitment the filmmaker has given to Karthi Sivakumar.

"After completing Oru Kal Oru Kannadi, I will start working with Karthi. Only after finishing the project, I will be able to start the Jiiva-Arya starrer," says Rajesh, who is working on the finishing touches of 'OK OK'.

On Tuesday, Hansika Motwani's birthday was celebrated on the sets of 'OKOK', with Rajesh and producer-actor Udhayanidhi Stalin taking part. "We had a nice time as there was a cake-cutting ceremony," the director says.

The talkie-portions of 'OKOK' will be completed by the end of this week. After that, Rajesh will start the post-production work, which may go up for nearly a month. "In all probability, the film will be an October release," say sources.
