I should structure the report into sections: introduction, plot summary, cast, director and production, reception, themes, and cultural impact. Make sure to highlight Aamir Khan's dual role if that's part of the plot, but from what I remember, he plays one character. Wait, no, the film has two main storylines with Aamir Khan and Kajol in both? Wait, no, maybe the other storyline is with other characters. Let me confirm. The film has two parallel timelines. One is the story of Rizwan and Ayesha, and the other is about a different set of characters dealing with a bomb threat. The timelines are intercut to build tension. When the bomb threat affects the main characters, it brings their stories together.
