Karan Johar's debut film saw the DDLJ couple recreate their onscreen magic.

Rani Mukerji was the third angle in the tale, and went to become a regular feature in all of Karan's directorial ventures.

Again, Rani was not Karan's first choice. Her role was first offered to Raveena Tandon, Aishwarya Rai, Karisma Kapoor, Twinkle Khanna and Urmila Matondkar.

For those who love trivia: Nikhil Advani, the director of Kal Ho Naa Ho, appears for a few minutes in KKHH, as the love-struck youth who gets interviewed by Neelam (who plays a television host).
