I'm not the heroine in 'Heroine': Aishwarya Rai

CANNES, FRANCE - Indian actress Aishwarya Rai Bachchan's next movie sees her playing a Bollywood superstar, but on Friday she said it would not be a biopic of her own glamorous life.

Promoting "Heroine" at the Cannes film festival, the former Miss World - who has starred in more than 40 Indian movies - said she will be creatively at the mercy of director Madhur Bhandarkar.

"It's not a biography, it's not an autobiography for sure," said Rai, 37, with a laugh as she fidgeted with her hair. "You hear this today, at the very beginning, so know this until the very end."

When asked by AFP how much of the story she could identify with, she teasingly replied: "That's to tickle your fancy."

"I think that is what the viewer will probably be searching for," she added, "but it must always be remembered that the actor does what the director has visualised and envisioned for a particular character.

"I'll be playing a character called Mahi, but it's a character that's been written and conceptualised by the director."

"Heroine" will mark the first time that Rai has worked with Bhandarkar, who has a track record of peering into the lifestyles of India's rich and famous with such films as "Fashion" and "Page 3".

Ronnie Screwvala, chief executive of producer UTV Motion Pictures, said "Heroine" - to start shooting in mid-2011 - was a movie written expressly with Rai in mind.

Explaining why he was launching the project in Cannes, Screwvala alluded to Rai's star power: "She is the brand ambassador for India and for Indian cinema when it comes to the French Riviera."
