The 61-year-old actor is all set to play a common man seeking revenge in the film and will go young for few flashback sequences.
Director Solomon Ahishor didn't want too much of special effects on his looks hence Shah decided to work on his body to have a naturally slim appearance.
"There is a portion in the film where Naseer saab will have to look 30. Being a thorough professional, he wanted to know how real he could look. And after a few intensive discussions, he was convinced. For a look test, we ordered a special wig. With makeup and some special effects, we were able to achieve what we wanted. He is busy losing weight," Ahishor said.
