The stars and director of upcoming film Dum Maaro Dum were in the city on Saturday to promote the flick. All those present at the O Hotel were in for a treat as AB Junior made an appearance along with Prateik Babbar,Rana Daggubati and Rohan Sippy. Incidentally,this is Sippy’s third film with Bachchan after Kuch Naa Kaho and Bluff Master and the film-maker is hoping for a good verdict from the audience. Most of the film has been shot in Goa . It is a suspense thriller that entwines three stories – of a young student,a cop and a DJ. It is a chor-police tale with lots of twists and turns and great music, Sippy said. Rana Daggubati,who romances Bipasha Basu in the film,said smilingly,I had a great time working with her (Bipasha). AB Junior,whose last film Game bombed at the BO,has his fingers crossed this time. He said,I sincerely hope that people like my character (ACP Vishnu Kamath) in the same way as they liked Salman Khans Chulbul Pandey (Dabangg)! Well,for that,we just have to wait for April 22 when the film will release across India and in the United States .
