In the past the pair has given memorable performances in films like Dilwale Dulhaniya Le Jaayenge, Kuch Kuch Hota Hai and Kabhi Kushi Kabhi Gham. Most of the film is going to be shot in California. Previously Kajol had denied working in Kabhi Alvida Na Kehna as it was shot extensively in the United States and her daughter Nyasa was very young.
But this time around the actress faces lesser problems shooting abroad as Nyasa is five year old now. The first half of the movie is based on a true incident that occurred in a couple's life and Karan Johar has already bought the story rights. SRK will play a Muslim who gets wrongly detained on a flight as his last name is 'Khan' and the authorities' think that must make him a terrorist.
