Banita, who plays a comatose girl in Shoojit Sircar's highly-lauded film, says a whole lot of homework went into playing Shiuli, the girl who plunges from a high rise to a near-death experience.
She says the most irksome part of doing this role was to cease all activity.
"I am not going to lie. It was quite annoying being still for so long especially when my eyes were shut. We shot the film chronologically, so I had my eyes closed for about a week.
"And then when I finally got it open, you can't imagine how how relieved and excited I was able to act conscious, even if it was only through my eyes.
"So I really tried to grab to take advantage of any moment I had to do something and by the time it came to a physically demanding scene, I was actually able to do it easily because I was so frustrated acting still for so long while everyone around me was up and about."
Banita could feel her comatose character's frustrations.
"We were both sailing in the same boat. Rather, not sailing' at all. When I finally got to move, it came out so well on-screen because there was that frustration within me as an actor of being immobile.
