The retired professional wrestler, who stands seven feet with an impressive built, plays the role of a super villain, Raka, in the Remo D'Souza-directed superhero film alongside Tiger Shorff and Jacqueline Fernandez.
"I haven't been given too many dialogues to say in the past. I was a little nervous as sometimes makers change it at the last minute. So I would be surprised how did it change? I had practised a lot," Nathan told PTI.
The "Mad Max: Fury Road" star says since he has been a wrestler, he was at ease doing action sequences in the movie.
"I am comfortable with action because of my wrestling background. It is my forte. We used to rehearse it and I used to pick it up quickly. I feel if there is something that you practise and do again and again, it becomes easy."

"I like the idea of the film. I felt it was perfect for me and my career. It's really utilising what I have (referring to his look). It is not just about senseless violence, it has great substance."
Nathan feels that children are going to love the film.
"The film is a complete family entertainer with a wonderful message. This film is for the kids and I am sure they are going to love it," Nathan adds.
