Heroine problem for Raviteja's upcoming movie 'Sir Osthara' seems to have come to an end. Buzz says, Richa Gangopadhyay has been approached for the lead role in 'Sir Osthara'. Director Parasuram who has earlier directed 'Anjaneyulu' will be directing this movie. Aswini Dutt is producing this movie under Vyjayanthi Movie. Prior to this, Amala Paul and Trisha have been offered lead role in 'Si Osthara' but both of them opted out of project for some unknown reasons. Raviteja and Richa have earlier acted together in super hit movie 'Mirapakay'.
