In the morning, the trailer and audio of Ra.One (Tamil) was launched by ace filmmaker Mani Ratnam and Superstar Rajinikanth's younger daughter Soundarya Ashwin respectively, at a grand function in Chennai.

In the evening, Rajinikanth, who had done a cameo in the film, unveiled the first look of the film. Happy about this, Shah Rukh tweeted: "So much been happening, working round the clock, today Rajni sir unveiled the first look of Ra One. The character super excited, in Chennai."

Earlier, speaking at the audio and trailer launch of the film, SRK described Rajnikanth as a great human being and said it was a blessing to shoot with him for Ra One. 

"Since my younger days, I've been a fan of Rajnikanth and I was impressed watching him shoot for a Hindi movie a couple of decades ago at Mumbai airport. I wanted to get acquainted with him. God has been kind enough to make me do a movie with him now," Shah Rukh said.
