MUMBAI: Producer Vijay, who is upbeat about backing his filmmaker-mentor Priyadarshan's next yet-untitled Tamil directorial, says composer AR Rahman is yet to be approached to compose the movie's background score.

"This project is very close to my mentor Priyadarshan sir's heart. Right now, he is busy with script work and we only plan to approach Rahman sir after we complete the film. If he likes the film, he will compose the background score," Vijay said in a statement.

The project reunites the team behind National Award winning Tamil drama ‘Kanchivaram’, which featured Prakash Raj and Sriya Reddy in the lead roles.

The film, which will go on the floors on 10 August, will focus on AIDS awareness. Priyadarshan has assured that the film is going to be hilarious.

The story revolves around eight characters that come to a pathology laboratory at 9 am to give their blood for an AIDS test.

"The events between then and 5 pm, when they get their result, is the story of the film. Be assured that everyone can have a hearty laugh till almost the end," Priyadarshan told IANS.

Award winning maverick cameraman Santosh Sivan will be wielding the camera for the film, and popular art director Sabu Cyril is on board, along with Beena Paul who will be the editor.
