Celebrity couple Sarathkumar and Radhika are reuniting on-screen for an upcoming film named 'Vaanam Kottatum'. Produced by Mani Ratnam's Madras Talkies, the story was written by the legendary filmmaker along with the film's director Dhana.

In the recent audio and trailer launch event, the well-known couple hit the stage together to give their speech and ended up entertaining the audience with their jovial and spontaneous conversation with the members of the film.

Radhika went on to share her experience working with Mani Ratnam and pulled his legs saying that he cast Aishwarya Rai instead of her in Ponniyin Selvan because of the slight difference in their body inches.

Sarathkumar had his share of fun on stage when he reminded his wife Radhika that she's already old to which she replied, "I know I'm old. It doesn't worry me."
