Word has it that AR Rahman may perform live at the much-awaited audio launch of Vijay’s Mersal, which will take place at Nehru Stadium in Chennai on August 20. "It's going to be a grand audio launch and Rahman sir may perform. He is yet to give his final nod but the makers are hopeful that he will accept the invitation and at least perform briefly," says the source from the film's unit. If he agrees to it, that will be the biggest highlight of the event.

Vijay plays a triple role in big budget film, which is bankrolled by Sri Thenandal Studios. The three roles feature him as a panchayat head, a doctor and a magician. In the poster, he’s seen sporting a twirled moustache and this is said to be from the period portion of the film.

Directed by Atlee, Mersal also stars Nithya Menen, SJ Suryah, Kajal Aggarwal and Samantha Ruth Prabhu. The film, which will have a simultaneous dubbed Telugu release, is set to hit the screens this Diwali.
