The 31-year-old actress said that she worked relentlessly for a year on the action thriller.
She told Press Trust of India, “Whatever was required in the film I was able to do myself and execute in a manner that was desired.
“The journey of the film was huge with action sequences, six to seven locations all across the globe. It was a very difficult film for me. We had a very strong team and we did everything we could.
“The stunts that you see in the trailer I have done myself mostly. You know if a good script comes then I would love to do solo action films. I don’t think physical challenges scare me provided I have time to train and prepare.”
