Can never feel 100 per cent secure in showbiz, says Katrina Kaif

With films such as "Rajneeti", "Ek Tha Tiger", "Dhoom 3" and "Tiger Zinda Hai" to her credit, she may have become one of the biggest female stars in Bollywood, but Katrina Kaif says it is tough to feel completely "secure" in movie business.

Katrina believes film industry is changing rapidly and to stay relevant one needs to explore new arenas in the showbiz.

"I don't think you can ever feel 100 per cent accomplished and secure in your career because it is a rapidly changing industry. Things are changing so quickly. But now I do feel comfortable and confident here," Katrina told PTI, over phone from London, where she will be celebrating her birthday tomorrow.

"I have had a career that has been successful. Going ahead, you have to put in that much hardwork, keep performing and keep doing films in new spaces that are not only challenging but also interesting to audience," she adds.

Katrina's last release "Tiger Zinda Hai", opposite Salman Khan, was a blockbuster and earned over Rs 545 crore worldwide.

In her next two films, "Zero" and "Thugs of Hindostan", the actor has teamed up one again with Shah Rukh Khan and Aamir Khan, respectively.

Looking back at the year, Katrina says, it has been "fulfilling and gratifying for me".

"This year has been really good for me, 'Tiger Zinda Hai' did very well and it was a new film for the audience and people appreciated it. It feels great that 'Tiger' franchise continues to be a success."
"The only film I will be working on next is the dance film by Remo D'Souza and there are few ongoing discussions but things are not finalised."
