Khushbu, an actor-politician now, had paired opposite Rajinikanth in the blockbuster Annamalai, besides Pandian in the past. The film has already set off a buzz as Rajinikanth has teamed up with director Siva for the first time. The cast is a star-studded one, with the others being Prakashraj, Keerthi Suresh, Meena and Soori among others. Responding to her starring along Rajinkanth, Khusbu said she was joining hands with him after 28 years and that the "joy (of it) is unique." "We have done many films, people accepted and liked us.. I had not been done Tamil films for 8-9 years and was waiting for a big" one, she said. Director Siva and Sun Pictures offered the character and "it is a different" one, she said in a video shared by Sun Pictures on its Twitter handle. Rajinikanth's next film is tentatively titled Thalaivar 168, suggesting it was his 168th flick. Siva, known for his successful collaborations with top actor Ajith Kumar, had earlier directed the blockbuster hit of the year Viswasam, starring the latter.
