When Om Shanti Om (OSO) released in 2007, it was not just a movie; it was a cinematic event. Marking the debut of Deepika Padukone and helmed by choreographer-turned-director Farah Khan, the film was a love letter to the Hindi film industry of the 1970s. It embraced the age-old Bollywood trope of "reincarnation" with such self-awareness and gusto that it became an instant classic. Shah Rukh Khan’s powerhouse performance, combined with chartbuster music and high-voltage drama, cemented OSO’s place as one of the most successful and beloved films of the superstar’s career.
