Vivek Oberoi does not like talking about his relationship with Aishwarya Rai.

Right now, he'd prefer talking about his new film, Kyun! Ho Gaya Na...

But he can't stop praising Ash, his co-star in the film, for her professionalism and discipline.

"She used to come two hours earlier just to do her hair. She does not wear a wig in the film. If the shoot was to start at 7 am, she had to come in at 5 am!" he says.

"It takes so much patience. The sad part is if there was dew in the night, her hair would straighten up. [Ash has curls in the film]. So she had to do it again. Yet, some people call her unprofessional. I am amazed!" he adds.

The actor discusses his new film, which releases on August 13, with News Editor (Entertainment) Syed Firdaus Ashraf.

Tell us about your character in KHGN.

Arjun, my character's name, does not take anything seriously in life. After he plays one prank, he is busy thinking about his next (prank). But sometimes, masti [playing the fun] is not good, as it can turn ugly. In this film, he makes fun of someone's emotions. Then he says, 'Pyaar aur haar Arjun ki dictionary mein nahin hain' [love and defeat is not written in Arjun's dictionary].

He does not like men running after women. He is a sportsman. In spite of being a modern guy, he believes in arranged marriage. My grandfather and father had arranged marriages and they led happy lives. So why should I opt for a love marriage, he feels.

He believes that arranged marriages have been going on for 1,000 years, so it is a superb formula.

I don't want to become Majnoo or Romeo in the film. But the heroine does not think that way.

Arjun never thinks of going to office or taking up his father's business. He only concentrates on having fun. He is very energetic, pompous and egotistic, but in a sweet way.

How close is Arjun to the real Vivek Oberoi?

I am a bit like Arjun in real life. But I think love is the best emotion. It connects you to someone else.

If you love someone truly, just look into her eyes. You will find your soul in her.

If you love a person truly, you can make an ordinary day very special for her.

If you go to see a film with a woman you love, then even if the film is bad you can hold hands and laugh at it.

What was the experience of shooting the film like?

During the shoot in Scotland, [director] Sameer Karnik made us really work. We worked 14 to 16 hours a day.

There, mornings begin at 3.30 am and it gets dark by 11.30 pm. So there is daylight most of the time. In this situation, if two actors come into the hands of such a director, then his day is done.

The weather was freezing and I had to wear only a shirt and shoot for a song. It even snowed. On top of that, they were splashing water on me! Just imagine my condition!

I tried to mouth the lyrics of the songs, but could not because I was shivering.

Isn't Sameer your school friend? Why didn't you ask him for a break?

(Laughs) He was never a friend while directing the film!

The other actors got a better deal. I had to work hardest because of Sameer.

I thought things would be easy because he was a friend. But he was very strict for me compared to the other actors. You see, if I shouted back at him as a friend, the others may have done that too. I kept this in mind.

Why are you doing films only with big banners?

This is not true. I am lucky that big banners are choosing me. It is the blessing of my elders. I am not in a position to choose directors. I am still learning. It is just that I am getting a chance to work with them.
