Katrina was sceptical to work with 'meticulous' Aamir Khan

Aamir, known as a perfectionist in the Hindi film industry, is sharing screen space with Katrina for the first time in 'Dhoom 3', releasing next month. They form the antagonist duo in the Adiya Chopra-produced action thriller.u00a0

"Initially, I was sceptical to work with Aamir because of his planned and meticulous nature...so I was nervous. But when we started working I found him amazing. He is a genius actor and treats his co-stars well," Katrina said.

The 30-year-old popular star has worked with all the leading Khans of Bollywood and felt all of them are talented in their own way. "They all share the same surname but they are different actors and have different style."

Talking about competition in Bollywood, the 'Welcome' actor said she takes it in a positive way. "I am extremely blessed with the way my career is shaping up.

I feel I got much more than I had thought. Competition is a good thing as it helps you to better your performance. Any competition is good," said the model-turned- actress, who has completed a decade in the film industry.

Katrina is not worried about 'Dhoom 3' being touted as a hero's film. "Today times are changing. All kinds of films are being accepted which is a good thing."u00a0
