Director Zoya Akhtar came up with some fabulous movies in the past few months. With films like 'Luck by Chance', 'Zindagi Na Milegi Dobara', 'Talaash' and her recent release 'Bombay Talkies', Zoya is now ready with her next film too.

Earlier it was heard that Zoya had already found her cast comprising of Hrithik Roshan, Kareena Kapoor, Ranbir Kapoor and Katrina Kaif (read news). Kareena and Ranbir were signed up to play siblings, as the story is somewhat based on the lives of Zoya and Farhan Akhtar.

But now, it is heard that Ranbir is too busy to give his dates and Zoya is not willing to wait for him. So now the focus is shifted on Ranveer Singh who seems very interested to work with Kareena as per sources.

Ranveer missed a chance to work with the actress in 'Ram Leela', so this time he wants to make it work, even though he doesn't get to play the romantic lead, said the source.
