Sliding Doors is a 1998 romantic comedy directed by Peter Howitt and stars Gwyneth Paltrow. The film employs a narrative device that splits the storyline into two parallel universes based on the two paths the protagonist's life could take depending on whether she catches or misses a train. In one storyline, Helen (Paltrow) makes the train, discovers her boyfriend's infidelity, and starts a new life. In the other timeline, she misses the train, remains unaware of the betrayal, and her life takes a different trajectory. This concept explores how chance and choice can significantly impact one's life. The movie did well at the box office and got favorable reviews.
