20 years the director added rakesh roshan followed up koi mil gaya with a sequel krissh 2006 and turned it into a franchise with krrish 3 2013 it was the lord of the rings movie series that inspired the director to turn koi mil gaya into a film franchise i had the idea of taking forward the story of koi mil gaya as the ending had potential i thought of a one line concept and discussed it with hrithik and he was overwhelmed with joy upon hearing it introducing a superhero film to the indian audience was a tricky job said roshan the director recalled how important it was to keep the film high on emotions for the indian audiences it was the first time we were to introduce a superhero film to the indian audience we did not have reference points from past indian films while there were international superhero films being made at that time the indian audience needed films that were high on emotions too the fact that krrish became a blockbuster was because it was a superhero film with a very human heart at its core full of emotions he added reports of krrish 4 have been doing the rounds for a while the director did not comment on the reports but said he would like to carry forward the franchise both as a story and as a visual entertainer since its inception koi mil gaya franchise has been an ambitious idea weve always upped the scale and the stakes my ambition is high to carry forward krrish both as a story and as a visual entertainer when we made koi mil gaya there was minimal use of vfx as it was a new concept only the spaceship scene had vfx rest was groundwork and a lot of hard work to create from scratch now with the technology of vfx at its peak we have set higher standards and are dreaming bigger he said koi mil gaya was based on a story by roshan who also cowrote the screenplay with honey irani sachin bhowmick and robin bhatt javed siddiqui was the dialogue writer music was composed by rajesh roshan
