Kaif spoke to us about her past five weeks in the UK, why her new project is not called London Ishq, and how UK fans can meet her at a special fundraiser screening of Zindagi Na Milegi Dobara.
How did the idea for a screening come about?
"My brother Michael is studying Furniture Design and Craftsmanship at Bucks New University. They are putting together an event that will raise money for an exhibition which is called New Designers. It is basically giving students an opportunity to exhibit their work and give them a platform to showcase what they are working on, and show their talent.
"So my brother came up with the idea of screening one of my films and doing a question and answer session and a general chat after the screening. I thought that it was a nice idea and I was happy to help him out."
How did you single out Zoya Akhtar's Zindagi Na Milegi Dobara over some of your other films like Rajneeti or Namaste London?
"I think it is one of the most current films that I have starred in. The other thing is that my family really liked the film and it is something which they found slightly more relatable. In terms of if you are going to do a discussion of a film at a university, this draws in what I would term the 'new wave' of cinema that we are seeing do well in our industry. It is slightly different from your regular commercial Hindi film, so makes an interesting point of discussion."
What scene from the film are you most proud of that your fans can look out for as they watch?
"If you ask me for my favourite scene, or is it my favourite film or performance that I have done for a film, I don't know if that can be answered. But for me, I feel the film as a whole works. Zoya got together a good group of people to all contribute to the film as a whole. I don't know if one person takes away the glory or the credit of the film. For me it was a team effort."
When Digital Spy asked the same question to Hrithik Roshan, he said his favourite scene was getting to jump out of a plane. But of course you did not get to do that.
"I did not, that is very true. I did get to do underwater scuba diving in the film, playing a diving instructor. That was definitely the most difficult thing that I have ever done. It was extremely terrifying and not something I would particularly want to do again, but I think it works well in the film."
When you meet with your UK fans, do you feel that you act as an inspiration for them to follow their own Bollywood dreams?
"I don't particularly know, and I wouldn't want to make a statement like that, you know to necessarily give that much importance to what I do. But I do think that there is a certain connection. I have spent some years here and my family is here - some of them. I think there is a certain connection, a lot of the films that I have shot here have really worked well for me.
"Every time that I have come here for an interaction - the last time was something we did with a radio station, where we had an audience interaction - it has been so much fun. It is not something I do often, but when I have I have really enjoyed it."
What are you planning to wear for the event? Something that Manish Malhotra suggests or the first thing that you pull out of your wardrobe?
"Actually I think it is going to be whatever I am wearing on set for the film that day, because I'll be coming straight after pack up of the shoot."
Will anybody from the film be accompanying you? Shah Rukh Khan, Yash Chopra? Anupam Kher?
"I am not too sure, I think I will just be coming."
What have been doing over the last five weeks when you have had time off from filming?
"Well, I have been catching up with my family and going out to restaurants, the restaurants here are amazing. I haven't been going out every night so much but have seen a bit of what is out there. I have been out shopping, playing a lot of Scrabble, a lot of card games and just spending time together."
You are coming to the end of your filming schedule in the UK. What is next? More work on this film, or back to Ek Tha Tiger with Salman Khan?
"Yes, I go back to India on the 27th and will start shooting again for Ek Tha Tiger."
What message do you have for your fans about the fundraising event on Saturday?
"It's a very special thing, and close to my heart because obviously I am doing something like this with my brother for the first time. When I usually do events here in the UK I don't always get the chance, so it is something I am really looking forward to.
"It is for a great cause and the students have worked really hard in an industry where - to be completely honest- there isn't the scope to always earn a lot of money in it. It is something they do out of passion. It is an artistic expression, and I can understand that and relate to that in some way, so I think it is something good to support."
What about your sister Isabelle [currently studying at Lee Strasberg Institute]. Any more news on her rumoured launch into Bollywood?
"Right now she is still doing a bit of stuff in America, so let us see what happens after that."
There were many reports in the media about your new Yash Chopra film being called London Ishq.
"It's a nice name, but inappropriate for this film and definitely not the name. That won't be the name."
Katrina Kaif will attend an exclusive screening of Zindagi Na Milegi Dobara at 7.30pm on March 24 at Bucks New University in High Wycombe, UK.
