/> After playing the archetypal whore with a heart of gold in her last two films Rani Mukherjee is all set to do a moral about-turn.

In her new under-production Yashraj film directed by Kunal Kohli Rani plays an angel who descends down to look after business-executive Saif Ali Khan's children

Quite a leap of fate. And why not? For an actress who has always taken grave risks with her career.

How does it feel to be playing an angel?

"Right now I'm not allowed to talk about Kunal's film. But yes, any opportunity to surprise yourself and the audience is welcome," says Rani.

Some of her critics have sniggered at Rani's back-to-back roles as a prostitute in Laga Chunari Mein Daag and Saawariya.

But Rani is unfazed. "What's the big deal? An actor's job is to play a variety of challenging roles. And I don't think anyone has the right to question any actor for his choice of oarts.

I can't be happy doing just good-women or bad-women roles. Luckily for me I got to play three different kinds of prostitutes in The Rising, Laga Chunari... and Saawariya.

You can call it my prostitute trilogy. I hope people will remember my three different portrayals of the Fallen Woman with affection."

For now Rani is happy playing the angel in Kohli's film. She's currently shooting for the film with Saif Ali Khan in Bangkok.
