Asked how he managed to impress the superstar and his daughter, Dhanush said: "To impress Rajinikanth, you just have to be honest and simple, and I am still trying to impress Aishwarya."
However, Dhanush says his wife is proud that he has a huge fan following.
"She is very happy and she is very proud...," he said.
Dhanush, who will be next seen sharing screen-space with Amitabh Bachchan in "Shamitabh", says it was a learning experience to work with the megastar.
