Katrina Kaif has tackled her transformation into a super spy with complete commitment says director Ali Abbas Zafar.

Tiger Zinda Hai is a high-octane espionage thriller set to global standards in its scale, vision and production values.

In the film, Zoya is an elite intelligence agent taking part in hand-to-hand combats.

Director Ali Abbas Zafar said, “In this film, Zoya plays a super spy.

"It was essential to understand how such agents think and operate. So, we got Katrina to train with real agents, used their expertise and experience.”

“For instance, as intelligence agents, you have to train a certain way to keep your mental balance in direst situations. Say you face someone who has a gun and you don’t.

"How do you still stay neutral and calm, and figure out the best possible way to counter and survive in such a situation. Katrina has really pushed herself for the part.

"She has also gone the extra mile to train in important nuances like aggressive hand-to-hand combat. The action that Katrina has done looks very real onscreen, despite being mounted on a grand scale.”

Working with specialized professionals to crack her role, Katrina also trained in adapting to nuances of body language, mannerisms and other minute details.

Tiger Zinda Hai releases on 22 December.
