'Kuch Kuch Hota Hai' completes 15 years: Uncommon facts about the film.

Its been 15 years since Karan Johar made his debut as a director in 'Kuch Kuch Hota Hai'. The film went on to become one of the biggest hits of Shah Rukh Khan, Kajol and Rani Mukerji's career. Here is a look at some uncommon facts about the film. 

Salman Khan won his first Filmfare award(Best Supporting Actor) for his role as Aman. 

Kajol and Shah Rukh Khan were the original choice for Rahul and Anjali. Karan Johar had worked with them in DDLJ, where Johar had assisted Aditya Chopra and had even acted in the film, so he knew the working style of the two actors. 

Rani Mukerji was roped in to play Tina at the last moment. The role was written for Twinkle Khanna, another of Johar's childhood friend whose pet name is Tina. Khanna had turned down the role

During the bicycle sequence in the 'Yeh Ladki Hai Deewana' song, Kajol lost control of her bike, fell flat on her face and was knocked unconscious while also injuring her knee. 

The scene at the end of "'Ladki Badi Anjaani Hai' where Kajol's sari flies in the air and Shah Rukh Khan realizes her love for her, was not originally in the script. Choreographer Farah Khan added it, believing it added a filmy touch to the scene.

During the first basketball game, we see Shah Rukh Khan and Kajol "supposedly" jumping high in the air to shoot a basket. The hoop was actually a bit low, and they used trampolines to jump. 

The entire film was shot in nine and half months with a substantial part of it shot in Mauritius.The title song was filmed in several locations in Scotland over ten days. 

Rani Mukerji, without being asked, read the script and volunteered for the part, which gave a boost to her career. 

Karan Johar wanted Rani Mukerji to be dubbed due to her husky voice, not knowing that her voice would become her trademark. Rani's voice in fact dubbed in a film called 'Ghulam' which released the same year.

Johar first wrote a story, which was a love triangle between a tomboy, a very pretty girl and a slightly insensitive boy, but he shelved the idea because he was not very satisfied with it. Then he wrote another plot about a widower and his child, which he shelved as well. Eventually he decided to merge the two stories into one.

Salman Khan's extended cameo was initially offered to Saif Ali Khan who turned down the role. 

Johar hired Sharmishta Roy as the art director and told him to produce something similar to Riverdale High School of the Archie Comics, with some 90210 influence as well. 

During Neelam Show, the scene just before Shah Rukh Khan speaks, there is a scene in which a guy pleads her girl friend to leave him because he has found a new girl. The guy's role was played by director Nikhil Advani and the new girl was Farah Khan.
