However the other side of the story goes thus: Mamta was initially offered the lead lady's role. But later the filmmakers decided to take Sameera Reddy and so pushed Mamta to the second slot. A dejected Mamta could tolerate that sudden twist in the tale.
Market value being a crucial factor in the film world, Mamta has come up with the safe version to save her face. By glossing over the whole issue of her demotion in the project, she announced her decision to walk out of the movie.
The actress has even issued strong statements to boost her flagging career, “I want my role to make a deep impact on the audiences mind. My roles in Malayalam and Telugu have always reached audiences well. Though the movies boast of big banner and stars, I want my character to impress the audience." Better luck next time Mamta.
