 The first leg of filming took place at Mumbai 's Film City where an elaborate set re @-@ creating Chennai ( then Madras ) of the 80s , was set up . The second schedule was shot in Ramoji Film City in Hyderabad . The song ' Ishq <unk> ' was shot at Bidar fort in Bidar , Karnataka . Filming was completed in September , before venturing into post @-@ production , ahead of the December release . Director Luthria wanted to depict a sense of discomfort between the film 's two lead characters , Balan and Hashmi , a " meeting of two completely different worlds " . So he didn 't allow them to interact and get comfortable with each other during film workshops ahead of the shoot . Since he considered them " the unlikeliest pair to come together " , he brought them together right into the shoot filming an important scene , where they had to insult each other . Though he was initially anxious , it all turned out well and he was surprised by the resulting chemistry .
