Bollywood actors Shah Rukh Khan, Saif Ali Khan, and Preity Zinta’s romantic drama film ‘Kal Ho Naa Ho’, Monday, turned 19.

To mark this occasion, director Karan Johar took to his Instagram and shared a string of throwback pictures which he captioned, “An entire lifetime of memories, in a heartbeat! This film gave so much more than just that – it gave me joy, unbreakable bonds, a different lens for story telling and of course – the last film set I could be on with my father. And for that, I will forever be grateful to this film! #19YearsOfKalHoNaaHo.”
