Before approaching Bollywood actor Akshay Kumar for the lead antagonist in the film 2.0, an official sequel of the movie Robo the makers had contacted some other actors including Hollywood actor Arnold and Ulaganayagan Kamal Haasan. Shankar pinned a lot of hopes on signing in Kamal Haasan for the project. But the universal actor has straight away rejected the role. The reason behind him rejecting the proposal was recently revealed by him. It is said that both Kamal and Rajini made a decision that if they act together in a film, the fans should not be annoyed. To overcome that, any of the actors had to produce the film.
In this case, 2.0 is not produced by Rajinikanth and Kamal can not interfere in the production after the film starting its production activities. As a result, Kamal Haasan denied the project. Kamal is currently busy with his upcoming film Sabash Naidu.
