As before we had in all his earlier films even Endhiran will have an 'athiradi' opening song for the Super Star. And it is sung by SP Balasubramaniam.

The song which goes like "Naan Kandathu aararivu, Nee Kondaahu erarivu/Naan katrathu aaru mozhi/nee katrathu nooru mozhi is written by Vairamuthu. We can expect AR Rahman would have weaved a magic around this hero worshipping song.

Meanwhile a reminder of the story of Endhiran. Rajni plays dual roles in Endhiran. One is a scientist and the other is a Robot. Scientist Rajni, Dr. Vaseedgaran creates a Robot with artificial intelligence – like that of sixth sense in humans – which looks just like a human and behaves too like a human to help mankind. But the robot later acquires more human characters. It falls in love with Aishwarya Rai and writes romantic poems. Knowing about the extra ordinary intelligence of the Robot the villains try to get control of the Robot and plan evil activities. Scientist Rajni then fights to save the Robot falling into the hands of the enemies and destroys the evil forces using the Robot itself.
