Priyanka feels responsible towards this film much more because of the faith put in by the boxer in her despite criticism from some sections that a North East actor should have played the Manipuri athlete in the film.
"I feel so responsible that Mary is okay with me, a North Indian, playing her. She said 'I would rather have you, an Indian, playing me on screen than some South Asian actress who looks like me'. I also believe that looking similar is important in a biopic but I have tried to tell her story and showed her real persona, so I am hoping people will like it," said Priyanka.
The actress said that the makers initially thought about casting someone who looked like Kom but later they decided to approach her.
"This film needs to reach wider audience. She has put faith and responsibility in me. I am grateful to her and her family, they have shared so many details of their life with me," Priyanka said while calling it "a great creatively satisfying experience".
The National award-winning actress says she tries to keep a balance between films with meaty roles and commercial cinema, where male actors take the lead.
"I will never stop doing big budget films, though I do try to have some substance in my roles but if it is not there then I don't mind doing such films because my commercial viability as an actress comes from successful films I do.
"That's the honest thing. If I have to do a film like 'Mary Kom', I need to do these big budget films," she said, adding that an actress' value in the industry is judged by her commercial success and not by the strong roles she does.
"It is a movie-making business and the value of an actress in Bollywood depends upon her commercial viability, which in turn depends upon box-office. It holds true for male actors too," Priyanka said.
The actress will be next seen in Zoya Akhtar's 'Dil Dhadkane Do' with Ranveer Singh, and her maiden production 'Mada mji', which will be helmed by Madhur Bhandarkar.
