Mumbai, May 13 (IANS): Filmmaker Omung Kumar's wife Vanita Omung Kumar, also the production designer for his film "Sarbjit", says creating a Pakistani ambience was a tough task for her.

"Creating Pakistan for 'Sarbjit' was a tough task for me. We could not go there to shoot for various reasons. So to find a place like a Pakistani jail was so difficult. Pakistan jails are very different. They are like huge and have major areas. The walls are like a fort," Vanita told IANS.

"So we went to Palghar fort and it was so interesting. They had these Islamic arches so I created the whole jail in Palghar. I have kept the beauty of the fort intact and it's completely in a real zone," she added.

Randeep Hooda plays Sarabjit Singh in the film, which is a biopic on the Indian farmer who was convicted of terrorism and spying in Pakistan and was sentenced to death.

Vanita, who is also co-producing the film, says it is very special to her.

She said: "Co-producing happened because this film is like our baby. A lot of hard work, passion, blood and sweat has gone into making this film. It's not just a film. It's like a mission and I just hope people feel the same way as we did while making this film. It's not just another film. It's a very special film for all of us."
