Actress Aishwarya Rai Bachchan, who will play Dalbir Kaur Singh in a biopic on late Sarabjit Singh, the Indian death row prisoner in Pakistan, may flaunt a de-glam look in the movie.

Dalbir is the sister of Sarabjit Singh.

The film's producer Zeishan Quadri told IANS: "The look is not yet decided, but whatever the demand of the character is, we will go with it accordingly. The research department will sit and decide on that, but yes it's a real story, so it will be a de-glam look."

The look test will be done on Aishwarya in July.

To be directed by Omung Kumar, the film will go on floors by October and will be shot in Punjab.

"We are extremely happy with the casting. Who better than Aishwarya can justify the role?" he said.
