It was Shraddha's eyes that made her the best choice for the role apart from the obvious reasons of her being a good actor, pretty and young.
Vishal Bharadwaj felt that Shraddha has the perfect Kashmiri eyes which he thinks are very expressive and beautiful. The actress' brown eyes talk a lot and she can convey a lot through them which is very rare.
The film is set in Kashmir and Shraddha plays the role of a Kashmiri girl.
So, we can say that Shraddha's eyes played a major role in getting Shraddha her next project, Haider.
