Sherawat told DNA India: "I was invited to a dinner in US. I had even confirmed that I was attending it. But then I got a call from [director] KC Bokadia that we have a press meet today. I had to make a decision. For me Dirty Politics is the most important film in my life.
"I remember making a comment that women are treated like cattle in this country but I received flak for it. But that proved right with all rape cases, etc. The way women are treated - I think I owe it to myself to be part of this film and I stand for it. For this story to be told to the public."
