Bollywood actress Asin says it is unfair to call anyone, let alone a heroine, a prop in a male-oriented film. She says whatever the role may be, a heroine plays a part only she can essay in a movie. "I don't think anybody is a prop (in a film). You need a female protagonist and only she can do the role. So it is not very fair to call anybody a prop," Asin told IANS.

After making her mark in the southern film industry, Asin made her Bollywood debut with 'Ghajini' in 2008. Since then, she has been a part of many successful films like 'Ready', 'Bol Bachchan' and 'Housefull 2'.

"I think I am satisfied with the roles which I have got. They have become hit also. It is not easy to come from south to the north. Both audiences want different (types of) heroines. So it is not like it is an easy task. Otherwise, everyone would be doing it," she said.

Even if any of her films don't manage to do too well, Asin knows how to take it in her stride. "Only two of my films have had an ensemble cast. I am proud and happy that I did those films as I formed many professional relationships with many stars. I am sure that there are better films ahead," she added.

Mostly all her Hindi films have generated success at the box office success. But she laughs it off and says her presence in a movie doesn't guarantee moolah. "I don't give any guarantee. But it has all been a success so far, thanks to god's grace. But I have no set formula. I work with teams who I like to work with. I think that is the formula. Generally I select universally appealing and fun scripts," she said.

Asin's new film 'Khiladi 786', co-starring Akshay Kumar, will hit the screens Dec 7. This is her second film with the star and Asin says she shares a comfortable rapport with him. She is playing the role of a Marathi girl in the film. "I am playing a Marathi character for the first time. It is not a delicate character. It is a bit rough. The girl is very confident, and the experience was fun," she said.
