"It was difficult because it was physically challenging for me. The action was a bit unreal. It was very raw and a normal human being can't do it," Kangana told.
"Our action director had come from China and the fight sequences were very difficult. Overall, I had to learn a lot for the film. I feel my experience with 'Krrish 3' was physically challenging," she added.
A sci-fi thriller, "Krrish 3" will take forward the story of a superhero, played by Hrithik Roshan, while Kangana is the superwoman in it.
"I always wanted to play a superwoman and I was happy to do this. This is one of my best performances. I only hope everybody praises our hard work," said the 26-year-old.
Directed by Rakesh Roshan, "Krrish 3" also features Priyanka Chopra and Vivek Oberoi among others. It is slated for a Nov 1 release.
After starting her career with "Gangster - A Love Story", Kangana did serious roles in films like "Woh Lamhe", but she also tried a light hearted role in "Tanu Weds Manu".
And now sci-fi with "Krrish 3". She is happy to be part of various genres.
"In the seven years of my career I have been only trying to do different roles. For me, trying different stuff is my priority. I have got acceptance in each genre and that's a great achievement for me," said the actress who won a National Award for her work in "Fashion".
