One of the main reasons the search for Kaho Naa Pyaar Hai movie with English subtitles is so high is academic. Film schools in the UK and US study this film for its "dual role" dynamic. The subtitles expose the meta-humor. When Raj initially rejects Sonia because he doesn't want to be a "replacement," the subtitle translates his sarcasm perfectly, highlighting how the film comments on its own absurd premise.
