"'Kuch Kuch Hota Hai' released on 16th October, 1998... I still remember all 120 kg of myself standing nervously at the premiere!!" Johar posted on micro-blogging site Twitter.
The movie, featuring Shah Rukh Khan, Kajol and Rani Mukerji, was Johar's directorial debut under his father, late Yash Johar's banner Dharma Productions.
A heartwarming story about love and friendship, the movie went on to win the National Award for providing wholesome entertainment, in 1999.
Johar is now a successful filmmaker, and quite fit and fine at 39.
