"We directly approached Aishwarya as I know her since a long time. After meeting her, she agreed to do the film in just 15 minutes as the role was demanding and she could see herself in the role. So she instantly said yes," Omung Kumar said on the sidelines of Smita Thackeray's birthday celebrations.
