Aishwarya Rai has also joined the team in promoting the magnum opus Ponniyin Selvan directed by Mani Rathnam lately. In one of those events, Aish shared a rare opportunity that her daughter got from the OK Kanmani director on the sets of PS I.

When asked what was Aaradhya's reaction, Aishwarya said, "At the time she was enthralled. Seeing a period drama is always exciting. And she did get the opportunity to visit on set. It was mesmerising (for her) and I could see that in her eyes. But I think my admiration for working with him (Mani Ratnam)...she respects him, she is in awe of him. And, I think what excited her the most was when one day she came on the set, he gave her the opportunity to say 'action'. She could not get over that. She was like 'aah, sir gave me that opportinity'. I don't think any of us had that opportunity. That's probably THE most cherished memory for her. She values it already and with growing years more so."

Ponniyinn Selvan's stellar cast is headlined by Chiyaan Vikram, Aishwarya Rai Bachchan, Karthi, Jayam Ravi, Trisha, Aishwarya Lekshmi, Lal, and Sobhita Dhulipala, among others. Its soundtrack has been composed by AR Rahman. The film's cinematography has been handled by Ravi Varman.

The two-part franchise has been shot on a budget of Rs 500 crore. Its soundtrack has been composed by AR Rahman. The film's cinematography has been handled by Ravi Varman. Ponniyin Selvan will hit the theatres on September 30 and will become the first Tamil movie to release in IMAX.
