She has been praised for being the voice for Nayanthara. Taking to Instagram, Deepa Venkat shared the poster of Aishwarya Rai from ‘Ponniyin Selvan’ and wrote, “What do I say about this? Going to crescent avenue and entering the studio of Madras Talkies is like going home. Warm, friendly faces and fun chats catching up with technicians and staff at the office.”

But every time I leave this studio, overwhelmed and with a sense of fulfillment. Being part of films like ‘Kannathil Muthamittaal’, ‘Guru’, ‘Cheliya’ (Telugu version of ‘Kaatru Veliyidai’), ‘Chekka Chivantha Vaanam’ and now, ‘PS-1’, has enriched me in more ways than I can think of. This is my first one, for the enchanting and deeply committed actor, Aishwarya Rai. I have more to share about her. But that has to be a separate post. Later:)) Mani sir, I can never thank you enough for this. Thanks for all the love, everyone.”
