Ranbir, Deepika share amicable equation: Ayan Mukherjee

One wonders if bringing old flames Ranbir Kapoor and Deepika Padukone back on screen for Karan Johar`s `Yeh Jawani Hai Deewani` was a tough nut to crack! But director Ayan Mukherjee says it was a smooth process as the two actors share an amicable equation.

"Actually it was very easy. I know that the media had written a lot about their break-up, but actually they have a very amicable equation and it was really smooth to put them together," said Mukherjee.

The two actors dated each other for over a year, and split in 2009. So far they have done one film together - "Bachna Ae Haseeno" in 2008. This will be their first film after the dramatic break-up in 2009.

But Mukherjee of "Wake Up Sid" fame is looking forward to bringing their sizzling chemistry on celluloid through the love story.

"It is a love story and I am really excited about my cast. I am hoping to start sometime around mid-January and hopefully will have the film ready sometime mid-next year (2012)," he added.

The title of the movie is inspired by the famous R.D. Burman song from the 1970s hit "Jawani Deewani", and the director feels the title is apt and youthful.

"The title is from an old song but it`s also a youthful title. I suppose it means the romance of being young and that is what it (the film) is about," he said.
