Aishwarya Rai Bachchan is elated at the positive response for her de-glam look in her upcoming film 'Sarbjit' has received.

The biopic on Indian convict Sarabjit Singh, who was beaten to death in a Pakistani jail, is being helmed by 'Mary Kom' director Omung Kumar.

Aishwarya is playing Sarabjit's sister Dalbir Kaur, while Randeep Hooda will be seen in the titular role. The shooting began this week in Mumbai. A picture from the set showed Aishwarya dressed as an aged woman, wearing spectacles.

"We have started filming and would like to first say that, the picture is already out and I am very thankful for the response... It has been very encouraging, even for the choice of subject. Work has begun and it is (the film) intense," the 41-year-old actress told reporters here at Stardust Awards.

'Sarbjit' is produced by Sandeep Singh, Kumar and Vashu Bhagnani. The film is slated to release on May 20, 2016.
