That's Aishwarya Rai, a former Miss world and she is simply smokin' hot!
The plot of the movie is: Dr. Vasi (Rajnikanth) invents a super-powered robot, Chitti, in his own image. The scientific body, AIRD, that must approve the robot, declines it based on its not having emotions and the ability to make rational judgment. A sudden flash of lightning evokes emotions in the robot, and Chitti is seemingly ready for integration into the human world. Then, Chitti falls in love with Dr. Vasi's fiancée Sana (Aishwarya Rai) and turns on his creator.
Made on a budget of Rs.180 crores (approx $40M), it is the most expensive Bollywood movie ever made and is the highest grossing Indian movie of all time! (Thanks IMDB!).
