Imtiaz Ali, we learn, wanted to ensure that everything shown in Rockstar is close to real life. This is possibly the first time that a Kashmiri Pandit wedding will be shown, with all its rituals and traditions.
Imtiaz met a Kashmiri Pandit family and enquired about their wedding rituals in great detail. He then visited the popular Kheer Bhawani temple, met the priest and watched his own daughter's wedding video to have a visual understanding of the rituals. Designers Manish Malhotra and Akki Narula researched on the traditional attire. From the way food is served in the tram (copper plates) to the traditional Dejhor, the Kashmiri jewellery worn in the ears (symbol of married women) along with shaneel fyran (velvet dress), the intricate henna pattern and the tarang (cap) the girl wears during the wedding rituals, etc, were researched for the shoot.
During the shoot, the locals who were part of the scene were given full freedom to inform Imtiaz if something was going wrong and wasn't part of the tradition.
