That didn't work out. Then, she was all set to serenade Sammir a second time in Chicago-based producer Masood Ali's film which was supposed to be shot in a start-to-finish schedule from mid-June.
But Tanisha has opted out of the film and chosen Uday Chopra over Sammir Dattani.
Doing a last-minute volte-face, she has chosen to do a Yashraj Film with Uday in Canada during the time when she was supposed to be shooting with Sammir in the US. This leaves Masood Ali's project heroine-less at the eleventh hour.
Surprisingly, Dattani is far from resentful regarding Tanisha's turn-around. "Of course, she should do the Yash Raj film over my project. If I were in her place, I'd do the same. It's my dream to work in a Yashraj film. I'm sure it will happen soon. I admire Mr Yash Chopra and Aditya a helluva lot."
And what's the Yashraj project that Tanisha has chosen? It marks the return of Arjun Sablok who directed Na Tum Jano Na Hum with Hrithik Roshan and Esha Deol three years ago.
"It wasn't a very happy experience for me. If I had made Na Tum Jano Na Hum for Yashraj Films, it would've rocked. I haven't met a single person who doesn't love the film.
That's why I'm glad to be back with Yashraj Films. I know my film's future is ensured. The biggest mistake of my life was to leave Yashraj productions. Now I'm back where I belong."
Why the long gap between his two films?
Explains Arjun, "I've been in-charge of Yashraj's ad cell for quite some time, made the popular ads for Hajmola and Dabur with Mr Bachchan and Rani. I also shot the Dhoom video with Tata Young.
When Adi suggested I write a script for Uday, I immediately thought of a romantic comedy about two absolutely mismatched souls.
Trust me, even if Uday wasn't a Chopra, I'd still cast him as my protagonist, Neel. And Tanisha fits the role of the female protagonist Nicky to perfection. I can't see any other actors in my film."
Did it hurt to see other Yashraj protégés like Kunal Kohli and Sanjay Gadhvi race past him? "I can't say it didn't hurt.
But everything in life has a reason. I think Kunal and Sanjay have done a fab job in Hum Tum and Dhoom. It's all karma. I think the time is right for me to make my second film. It couldn't have happened earlier or later."
Arjun shoots his film in his hometown Vancouver from June 15. "We wrap up in one schedule.
Apart from Uday and Tanisha, the rest of the cast will comprise completely new faces. It's a film where I want to project a certain freshness. Even Salim-Suleiman's music exudes that ‘wow-isn't-that-something' appeal."
