'Rahman and I kind of discovered each other during 'Rang De Basanti' (RDB). With him, it's not project-to-project ... Ours is a collaborative effort and it's a great team,' Mehra told IANS.
The two not only meet and talk but also keep in touch via the Internet.
'We keep meeting, talking, discussing ideas over the Internet and Skype (Internet telephony) about the movies I want to make and about the music he's churning, etc,' the director added.
