Actor Imran Khan believes his forthcoming film "Matru Ki Bijlee Ka Mandola" deals with a somewhat taboo subject and this may give rise to some controversy before its release.

"It's a very taboo subject. Not controversial but people can find a way to make it controversial," the 29-year-old said here Tuesday at a radio station.

"I'll tell you what will happen, one week before the release someone will find a way to make it controversial, someone or the other will get offended, just see," he added.

His co-star Anushka Sharma chipped in, "It is what it is."

The film is set in a village where Anushka plays Pankaj Kapoor's daughter, while Imran works with Pankaj. However, problems arise when Anushka gets involved with another man, Arya Babbar, a powerful politician Shabana Azmi's son.

Anushka, who plays Bijlee, said the role was quite tough for her.

"For me the role was difficult to play because of the way I am, I say whatever I think. But Bijlee is somebody who holds her emotions and her thoughts to herself," the 24-year-old said here.

"She portrays an image that is not maybe who she is. So I think that was a little difficult," she added.

Directed by Vishal Bharadwaj, the film releases Jan 11.
