If the project materialises, Ranbir will be working with yet another accomplished filmmaker. He made his debut with Sanjay Leela Bhansali's 'Saawariya' and later featured in Siddharth Anand's 'Bachna Ae Haseeno'.

Currently, he is working with Raj Kumar Santoshi in 'Ajab Prem Ki Ghazab Kahani', Prakash Jha in 'Rajneeti', Shimit Amin for the forthcoming 'Rocket Singh - Salesman Of The Year' and Ayan Mukerji in 'Wake Up Sid'.

When asked about it, Imtiaz said: 'Honestly speaking, nothing has been finalised yet. Yes, Ranbir and I have been meeting each other for quite some time and have been bouncing off story ideas. Still, we are yet to close on a story line.

'I have always placed my story before anything else. Whether it is 'Love Aaj Kal', 'Jab We Met' or 'Socha Na Tha', the story has always been of paramount importance.'

So is he or is he not signing Ranbir?

'I definitely want to work with him. However, I will announce my cast once the story is finalised. Making any comments before that would be immaterial and unwarranted,' he said.
