Siva Karthikeyan is also acting in this movie. Atlee and Siva Karthikeyan are good friends. Atlee made some short films before becoming a director. Siva Karthikeyan also acted in them. Atlee wanted to take Siva Karthikeyan in the movie 'Raja Rani' itself, but it didn't work out then. But now it has worked out.
However, the question is whether this young hero, who is going strong as a hero with movies like Amaran, achieving 300 crores, will act as a villain in Bunny's movie or not. Is he being taken for the villain role at all...? Or is Siva Karthikeyan going to be seen in some other important role?
