Apart from the very fact that both are India's first sci-fi thrillers, there turns to be yet another connection between these flicks. It all started after the release of superstar Rajnikanth's Endhiran.

Soon after watching the film Robot (Hindi version of Endhiran), it seems that SRK called for a SOS meeting with his technicians to make some changes in his script. It was all about adding more emotional quotients to this sci-fi thriller.

Academy award winner Resul Pookutty is yet another commonality and he has already gained the laurels for his best sound in Rajnikanth's film. Resul has been putting on more efforts to bring the best sound with Ra One.

Recently in an interview, he uncovered a striking similarity between these films. Both of them have a mind-boggling train chasing sequence. However, SRK has decided to re edit the shots and add flavors to it so that audiences don't term it as a 'copycat'. The sources reveal that the action sequence has been shot at a cost of Rs. 3 crores.

Huge money, new ideas and themes and realms of Superstars – wow! That's about launching Indian films in international standards.
