Sridevi's double role in Khuda Gawah was one of her best. Her multiple looks were gorgeous in the film. As Benazir, of Afghan origin, and as the younger Mehendi, she had two distinct looks.
Fierce as the mother, feral as the younger, there's no single actress who can do a double role as well as Sridevi. She carefully constructs two distinct looks, personalities, even vocal tone to essay two roles in the same film.
