Katrina: Bang Bang was a difficult film

Katrina Kaif has described Bang Bang as the most difficult film of her career.

The 31-year-old actress said she worked relentlessly for a year on the action thriller.

She told PTI: “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.” Starring Hrithik Roshan, the film has been described as a remake of Knight and Day.
