Lilette Dubey's toughest scene

It still sends shivers up my spine – the scene in director Sudipto Chattopadhyay's Pankh.
It was the end of the film and what a surreal one at that. My character of the ambitious cold-blooded mother, who pushes her son into cross-dressed, gender-converted film acting finds her son in a swimming pool filled with blood. However, the catch is that it isn't very clear to the audience or to me whether my son is truly in a pool of blood or I'm imagining the whole thing.I had to cry as I swam through the cold, blood-red water.
It had all the elements of a Greek tragedy. It had the same implosive unstated intensity as Andromache wailing for her son except that unlike the Greek play, my co-actor Maradonna Rebello, who played my son in the film, was supposed to be dead.
So there I was, alone in my space, with all my character's anguish and pain. Luckily for me, my director was extremely supportive. Thanks to him, we kind of swam through that murky metaphorical scene.
