AR Rahman's speech at 2.0 Trailer launch:
"When Shankar told me the situation, I didn't understand. He didn't accept all my tunes initially. After giving like 12 to 13 tunes, he finally liked this tune.
We composed the OST for
2.0 in London, Chennai and Delhi. We are planning to release a set of the background one week before the release. Shankar initially started the film with no songs, then we had 2 songs now the film has 4 songs in total."
When Anirudh asked 'Isai Puyal' on who his favourite actor is, AR Rahman said - "I told this 10 years back that it is Rajinikanth. I like him for various qualities that he poses. He's an inspiring personality. I admire his consistency, spirituality, punch dialogues, and desire even at this age. I wanted to retire at 40 but he changed my mindset."
