As Kal Ho Naa Ho re-releases in theatres today, filmmaker Karan Johar could not resist looking back in time and cherishing the moments he created while making the hit film, which starred Shah Rukh Khan, Saif Ali Khan and Preity Zinta in the lead roles. Taking to Instagram, Karan dropped a video showcasing iconic scenes, dialogues, and songs from the movie. "Hasso, jiyo, muskaraao...AAJ kyunki kya pataa kal ho naa ho! A film extremely close & special to my heart...now back on the big screens for you all to witness and celebrate again," he captioned the post.

Released in 2003, Kal Ho Naa Ho also features Saif Ali Khan and Jaya Bachchan. It revolves around Naina Katherine Kapoor (Preity Zinta) who is an MBA student in New York. She falls in love with her neighbour Aman Mathur (Shah Rukh Khan), a terminally ill patient who tries to get Naina and her friend Rohit Patel (Saif Ali Khan) to fall in love with each other since he fears she will grieve for him if he reciprocates her feelings.On film's 20th anniversary last year, producer Karan Johar penned a lengthy post saying, "This film has been such an emotional journey for me and perhaps for all of us, if I have gathered over the many years. To bring such a stellar star cast together with a story that has a beating heart...it's all kudos to the entire cast and team behind the camera for making Kal Ho Naa Ho still beat strong and within everyone's hearts."He also revealed that 'Kal Ho Naa Ho' was the last film his father (Yash Johar) was a part of from the Dharma family."For me, this was the last film that my father was a part of from the Dharma family...and it feels surreal to have his presence in every frame as I rewatch it even till today. Thank you papa, for guiding us through everything & making stories that matter...and for always standing by what is right. I will always miss you," he added.'Kal Ho Naa Ho' is still remembered and loved by people -- especially for actors' emotional performances, songs and dialogues. Who can forget Shah Rukh's iconic love confession: "I love you very much Naina" while reading from a blank diary? Also, one can't also forget his "Haso, Jiyo, Muskurao, Kya Pata Kal Ho Naa Ho" dialogue.The film will mark its 21st anniversary on November 28.
