Kamal Haasan admits he was offered the villain's role in the sequel to Robot with Rajinikanth. But he declined the offer even without considering it.
The real reason for saying no to Robot was something else.
Explains Kamal Haasan, "Rajniji and I have a pact. Whenever we do another film together it'd have to be produced by either me or him. It's the only way to ensure we do not displease our fans."
