Katrina Kaif is currently preparing for her next film Tiger Zinda Hai for which she is learning difficult stunts. Also Kat for her role in Jagga Jasoos prepared so hard.

A source said, "Kat plays a journalist and she had been living the character for several months. She always knew that this character would need extensive preparation, and wanted to get the mannerisms right."

Added the source, "She would watch behind-the-camera footage of journalists and how they approached their stories. She also watched a few famous movies and referred to books to understand the kind of questions they ask their subjects."

Katrina also said, "The beauty of being an actor is that I get to play different characters. Each character has its own graph and needs some amount of preparation and that's what's exciting and challenging too."
