A plan was etched to rope in the Big B, Amitabh to enact in the climax sequence of this movie. The actor gave his consent to play the role but unfortunately his dates didn't fall in place.
Adding to this, Amitabh fell ill recently and was admitted to the hospital. With no other go, the makers of 'Aruvadai' made a decision to cast another popular star and continue with filming the end portion of the movie.
Pairing up Malayalam superstar Mammootty alongside action king Arjun adds hype to the movie that is under making to enthrall the audiences of Kollywood and Mollywood together.
