Mumbai, Oct 3 (IANS) Katrina Kaif says that she neither thinks about the cast nor script while signing a film and adds that her decision is influenced by her thought process at that particular moment.

"I don't calculate and choose scripts. At that moment of saying yes, I would have something in my mind that this is what I want to do," she said.

"When I signed 'Dhoom 3', I was sitting in my car. I was listening to a song and I thought I want to do something different with the songs I am doing and that I want to dance and that film ('Dhoom: 3') seemed to be the best space to do it in," added the actress whose latest film is "Bang Bang!", in which she is seen with Bollywood superstar Hrithik Roshan.

In fact, in her last few releases she was seen with Bollywood's top notch Khans - Aamir was her co-star in "Dhoom: 3", Shah Rukh in "Jab Tak Hai Jaan" and Salman in "Ek Tha Tiger".

When asked are you working with superstars by choice or design, she said the cast depends upon the script.

"I don't think anyone approaches me with a (pre-decided) cast. Out of my last five films, I was on board of two even before the male actors were signed on. If it's a good script, by default you would get a well known actor or big star."

"In terms of who comes with which actor, I don't see it that way. One of my next films is 'Fitoor' by Abhishek Kapoor. When he signed me on, there was no actor on board. Later they roped in Aditya Roy Kapur. That time I had not seen 'Aashiqui 2', but I didn't question the director. That is his decision, his vision and I go by that.

"When I did 'New York', Neil Nitin Mukesh was one-film-old. When I worked with Imran Khan and Ali Zafar (in 'Mere Brother Ki Dulhan'), they were new. I have worked with new people as well," she added.
