Aishwarya Rai, who is working with Rajinikanth for 'Robot' can't stop gushing about the actor.  

'It was great working with Rajinikanth, who is a brilliant actor. The only tough thing about the movie was studying Tamil again in order to pronounce the words properly,' she said.

'Robot' directed by Shankar brings together Rajinikanth and Aishwarya Rai for the first time. A couple of song sequences were shot recently in Peru.

Says Aishwarya,” Shankar had approached me previously to work with him, but could not be materialized. Finally, everything landed in place and here we are together after ten years.” 

Other than this, the actress will soon start acting for Mani Ratnam's ‘Ravana’ with her husband Abhishek Bachchan.

“I don't want to reveal much about it but in another 10 days, we will start shooting for the movie. I am looking forward to working again with Mani,” she added in an interview to a news agency.
