/> Upen Patel is currently shooting in utmost secrecy with Ranbir Kapoor and Katrina Kaif for Raj Kumar Santoshi's ajeeb-titled Ajab Prem Ki Ghazab Kahani.

What would Upen be doing in a film which has Ranbir Kapoor playing the title role ?

"It is the love story of Ranbir and Katrina, no two ways about it, " admits Upen. "But I don't have a flimsy part at all. No way. I've 40 days of work in the film.

I come into the plot like Salman in Kuch Kuch Hota Hai. But my main reason for doing the film was of course Raj Santoshi. When he offered me a role I felt ten-feet tall.

When I heard the script I fell in love with my character. No way was I going to miss the chance of being in this film just because another actor had the lead."

Upen is under strict contract not to reveal any details of the plot. "But the biggest compliment I got was when Rajji said he was making a comedy after 14 years.

And if Ranbir was like Aamir in Andaz Apna Apna I was like Salman in that film. The faith that he has shown in me is precious. I'm working hard to live up to his faith."

And this time, Upen is pretty sure Katrina would prove lucky for him as well. "Katrina and I were in Namaste London together. And look where that film took her."

That wasn't such a pleasant experience for Upen. "But this time we'll be far more relaxed. We're both Londoners, remember?

We were both raw and new when we did Namaste London. Look how lucky she is for her movies. Hope she proves lucky for me as well."
