What isn't so well-known is that the project has been struggling to find itself an appropriate title.
Finally the film has the title it has been looking for.
The Ranbir starrer which has the young superstar courting Bipasha Basu, Minissha Lamba and Deepika Padukone, is called Bachna Ae Haseenon....
The title immediately takes us back to Ranbir's father Rishi Kapoor's chartbuster in Nasir Husain's Hum Kissi Kam Nahin.
Laughs Ranbir, "But I don't think we decided to name the film Bachna Ae Haseenon to suggest a link with my past.
Sure, the song was a big R.D. Burman chartbuster in its time. My dad, mom and I are all huge fans of RDB. My parents biggest hits were composed by RD.
But more than the instant connectivity I think the title was selected because it's very apt for my film. It's about this guy's journey in life and his different encounters with various women."
Bachna Ae Haseenon is 60 percent complete. It's expected to be released on 15 August.
