Mumbai, Aug 11 (IANS): Filmmaker Aanand L. Rai has rubbished rumours that he has cast actress Parineeti Chopra in his next film starring superstar Shah Rukh Khan. He says he is yet to zero in on a leading lady.

When IANS contacted Rai asking him if he has finalised Parineeti for the movie, he said: "No, all these speculations are happening because of me... Because I am not touching the finishing line and coming up with the cast."

"These speculations are happening because of my laziness, but yes I will take a couple of weeks to take a call. I'm in talks with a few actors, but none of them has been finalised."

Asked if he has even approached Parineeti, he said: "No, I haven't. Give me two weeks and I will be able to talk about it in a better way."

Rai, who has made "Raanjhanaa" earlier, also said it is going to be a very tough film for him.

"It's a tough film for a person like me because this film will have everything, but technically it's challenging for me. The visual effects work for this film is something which will be very challenging for me as a director," Rai said.

Meanwhile, Rai is busy with the promotions of his production "Happy Bhag Jayegi".
