Rajni plays Robot in Ra.One

Rajinikanth does a cameo in the science-fiction film `Ra.One`, for which, he flew to Mumbai to shoot a scene on Sunday. Accompanied by his daughter Soundarya, Rajini took one day break from his acting sabbatical, as he is recuperating.

"Rajini sir will be seen in Chitti`s avatar. He was here to shoot. It was heart-warming to see him. We were all overwhelmed," Shahrukh told reporters .

Describing the scene, Shahrukh said, "When we devised it, he was unfortunately unwell, so we couldn`t do it that time.

It is a funny scene where G.One tries to save Kareena and his son. He is fighting with the goondas and suddenly Chitti, the robot, comes. I ask Kareena who he is, but she does not respond. There is an interesting part here."

"When I dance on `Chamak Challo`, I wear a scarf, the movement...walk and all G.One learns, adapts from Rajnikanth`s character Chitti. It is a tribute to Rajini sir," he said.

In Shankar`s science-fiction film `Endhiran`, Rajinikanth had played dual roles - as a scientist and an android robot.
