I have a pretty serious hunch that the concept of Kuch Kuch Hota Hain(1998) was derived from the movie My Best Friend's Wedding (1997). I acknowledge that the story-lines are completely different. Anyways, both deal with deep friendship between hormone-laden male and female counterparts. from MBFW . from KKHH.. . Bottomline: When hormones from opposite-sex hormones communicate, the bodies give in..
