Superstar Rajinikanth's upcoming film Thalaivar 168 is one of the much-awaited films on Kollywood. The reason behind this is the director of the film Siruthai Siva, who gave back to back blockbusters in the form of Viswasam, Veeram, Vedhalam, etc. The growing cast of the film is the other reason for its hype. It is already reported that the National Award-winning actress Keerthy Suresh is on board for the film. The latest interesting buzz that cropped up about Keerthy's role is that she will be seen playing sister to Rajini and not his love interest. The film which is currently underway also stars senior actresses Meena and Khusboo in prominent roles.
