Priyanka Chopra, who plays a murderous wife to seven husbands in upcoming movie Saat Khoon Maaf says she was nervous when director Vishal Bhardwaj approached her with the role.

Saat Khoon Maaf, inspired by Ruskin Bond's short story Susanna's Seven Husbands, sees Priyanka, 28, playing a complex character once again after Aitraaz and Yakeen.

"The film is a black comedy and Vishal's version of humour. It's a very incredible film and a challenge for me. I was scared when he chose me to do the film. It's been a very difficult experience since I am portraying a wide age graph from a 25-year-old to a 65-year-old woman," Priyanka said in an interview.

Priyanka's character in the movie bumps off her seven husbands, played by actors like Naseeruddin Shah, Irrfan Khan, John Abraham and Neil Nitin Mukesh in the movie.

"Isn't it every woman's dream to kill her husband?," joked Priyanka when quized about her role.

Apart from Saat Khoon Maaf, the former beauty queen is also excited about Sidharth Anand's Anjaana Anjaani opposite Ranbir Kapoor, which hits theatres next month.

"Anjaana Anjaani is about two individuals who decide to commit suicide after several failed attempts at love. They come to the same bridge to do so and the ironic encounter becomes the starting point of a long-term friendship," said Priyanka said.

The National-award-winning star, who recently launched her own website, has been appointed as a UNICEF ambassador, a role which will see her working for girl education in the country.

"Twitter and my website are going to be prominent parts of spreading the message of girl education. We are a youth driven country and we need a push," she said.

She will also be making her debut on the small screen as a host of a reality show but says films will always remain a top priority with her.

"Movies are my priority. I am actor and I am getting to do all this because of that. I have two films Don-2 and Anurag Basu's Silence," said Priyanka.

"I am a multitasker and I get bored doing one thing. I am always involved with a billion things and really enjoy my work. I didn't knew I'll be an actor as I was going to be an aeronautical engineer after school. I've been fortunate enough to be given opportunities, work with best of directors and best co-stars. I don't think of tomorrow. That's boring," she added.
