The actor also confessed that he had watched back-to-back shows and added: "Of course, Urmila was also another reason!" evoking laughter from those present.
Turning to Aamir Khan, he said: "A huge fan of your films sir, I didn't believe I'd get to release a movie of yours or work with you."
Addressing the audience, Udhayanidhi said, "We are releasing a lot of films through Red Giant Movies. Almost once every two weeks, we are releasing a film. I was therefore looking to avoid releasing any more films.
"I didn't have plans to release this film. However, when Aamir Khan sir himself came on a video call and asked me if I could release his film through Red Giant Movies, I immediately said 'Yes'. I hadn't even watched the film then.
"Sir then made arrangements for me to watch the film. I have seen the film. It is extraordinary. A truly world class film. Aamir Khan has proved once again that he is one of the best, not only in Indian cinema but in world cinema as well."
The ace producer also said: "We are talking about pan India only now. Aamir Khan sir has been a pan Indian star for 25 to 30 years. It is a great honour for me to work with you sir."
