The world would have thought that with Abhishek Bachchan, Priyanka Chopra and John Abraham, Tarun Mansukhani had found his perfect star cast for Dostana. But wait, that's not the case.

And that's because without the man who plays the fourth most important character in this Karan Johar film, Tarun may not have been as ecstatic as he is today.

The man is none other than Bobby Deol and as per Tarun; Dostana wouldn't have been the project it is today if not for the presence of Bobby Deol.

Though Bobby's presence in the film has met with mixed reactions, Tarun continues to stand by his man who he believes was the first and the last choice for the role. Also, the one which was THE most perfect!

"When I wrote the part for this particular character in Dostana, Bobby was the first person I could think of. Even though I didn't know him, I knew that he had to be in the film.

Karan (Johar) gave him a call and his first response was not too encouraging. He point blank said that he wasn't quite willing to do the kind of role he was offered", details Tarun.

It was almost a fairy tale outing for Tarun who felt that he had lost Bobby for Dostana. "Somehow the meeting was arranged with Bobby and I asked him whether he was interested in me narrating only his part or the entire film.

Since he had the time, he gave me a go ahead to narrate the whole film. What happened next was truly surreal. He was rolling away with laughter and stated then and there that he would love to be a part of the film."

Tarun couldn't hide his shock though. "I was completely taken aback since I wasn't quite hoping him to say yes so soon.

I was quiet and it was only when Bobby asked me whether I still wanted him for the film that I came back to my senses. It was like a dream coming true because he is such a fantastic human being, a talented actor and an ultra professional."

Talking about professionalism, Tarun reveals, "For a 9:30 am shot, he would be ready at 9:25 am. He is a blue blooded person and truly a film royalty. When he stands up, he has a persona of his own.

Really, this role had to be done by Bobby Deol. I would have been crushed if Bobby would have said, No. Though he has a special appearance in the film, it indeed has in true terms being extra special for me."
