Actress Priyanka Chopra chooses to stay mum on speculations that she has been approached for a proposed biopic on Kalpana Chawla, an Indian-American astronaut.

"There are bunch of films that have been offered to me, I can't commit which one I am doing. There are few really amazing scripts. I have lot of choices, but not much time," Priyanka said when asked if she would be part of the Kalpana Chawla biopic.

Kalpana first flew on space shuttle Columbia in 1997 as a mission specialist and primary robotic arm operator. In 2003, she was one of the seven crew members who died in the space shuttle disaster.

Priyanka has been part of biopic "Mary Kom", and the film had got good response from everyone.

"There are six films, I can do only two between India and America. I don't know what I will end up doing. It's difficult to decide," she said.

The 33-year-old actress reveals that due to the success of American TV show "Quantico", it has got extended and hence she can't do many films.

"The show 'Quantico' has got extended so I am caught up with it. We have dubbed 'Quantico' in 44 languages like Italian, Spanish, German, etc. We have got very good response for the show...so from 13 episodes to 22 episodes," she said.


"I did not expect this kind of response for the show.

I can only do two films and I am in a predicament of deciding what to do next," she said.

There is buzz that the "Barfi!" actress is likely to team up with director Sanjay Leela Bhansali for a third film.

"We have been speaking for three-four films of which one to do first. He also has to make his mind which he wants to work on first. I am limited for time," she said.

Also, there were reports that Priyanka has been approached to be part of Salman Khan-starrer "Sultan", but she rubbished them.

"I have never been approached for 'Sultan'," she said.
