Sheetal Menon
For me, the most haunting aspect of the movie was the Khoya Khoya Chand music and sequence. The second thing that stayed with me was Sheetal Menon's performance. She was the only female "actor" in the movie. Unless I am mistaken, she had exactly ZERO dialogues in the film (well, maybe a word or two at the Divorce registrar's office). To be able to make such an impact with only her eyes and expressions, is the mark of a great actor. I look forward to seeing more of her.
Surprisingly, her performance has gone unsung amidst the more glamorous, blood-soaked images from the film.
