"Anurag and me - we will work together at some point. We have no plans right now as we don't have a script right now. We have our whole lives ahead. Even if he casts me when I am 65, I am happy. We will find our way, it has to happen naturally, " said the 29-year-old actress who married Kashyap in 2011.

Keen to do Tamil film
Kalki Koechlin, who has been part of Bollywood for the past four years, wants to do a Tamil film because she can speak the language, but rues that nobody has approached her so far.
"I would love to do a Tamil film. I can speak Tamil. I would like to do regional films, which I am comfortable talking. I am quite open to do Tamil films, but sadly nobody has approached me to do a Tamil film, " Kalki, the Indian actress of French descent, told.
Seen in films like "Dev D", "Shaitaan", "Shanghai" and "Zindagi Na Milegi Dobara", the actress says if she had not made it big as an actress, she may have needed a psychiatrist.

Kalki will be seen next in "Ek Thi Daayan". In Kannan Iyer directed film, the 29-year-old has teamed up with Emraan Hashmi, Konkona Sen Sharma, Huma Qureshi among others. The film is slated for an April 18 release.
