Actor Parag Tyagi, who last essayed the role of a ferocious monster in the TV show “Brahmarakshas – Jaag Utha Shaitaan”, will soon be seen sharing screen space with megastar Amitabh Bachchan in the third installment of the popular crime-movie “Sarkar”, says a source. “Parag will essay a villainous role who is mute,” said a source. He has already started shooting with Big B, who had played an integral part in the first two instalments of the film. “Sarkar”, which released in 2005, is set in the world of Indian politics and the underworld. Its sequel “Sarkar Raj” hit the screens in 2008. Directed by Ram Gopal Varma, “Sarkar 3” will see Amitabh reprising his role as Subhash Nagre. The film will also star Rohini Hattangadi, Jackie Shroff, Manoj Bajpayee, Ronit Roy, Bharat Dabholkar and Yami Gautam.
