It is no secret that the friendship of Superstar Rajinikanth and Kamal Haasan goes a long way back. At the beginning of their career, the duo has shared screen space in a number of films. Then, they mutually decided not to share screen space to concentrate on individual careers. Recently, when director Shankar approached Kamal Haasan to play the antagonist, the actor politely refused the offer. People speculated that this was due to Kamal's apprehension to play the baddie, but the actor has clarified it. He said that the denial was due to the secret pact and the duo would act together only if one of them bankroll the project.
