Aishwarya portrays the role of queen Nandini, while trisha plays Princess Kundavai. In the story, there are two antagonistic individuals. The main highlight, according to critics, is a final face-off scenario between these two in ponniyin selvan I.
The director reportedly warned trisha and aishwarya Rai not to become close friends off-camera. Working with aishwarya was mentioned by trisha Krishnan. "On the first day of my shoot, I was fortunate enough to get to know her and engage with her. I don't even need to remark that she is stunning on the inside and out. The problem is that despite the fact that we got along brilliantly on set, we are not supposed to like each other all that much in this movie. Mani sir would occasionally appear and tell the group, "Listen, you guys are pushing it too far; stop talking; I can't have this camaraderie for my scene."
