Sliding Doors is a 1998 romantic comedy-drama film written and directed by Peter Howitt and starring Gwyneth Paltrow while also featuring John Hannah, John Lynch, and Jeanne Tripplehorn. The film alternates between two storylines, showing two paths the central character's life could take depending on whether she catches a train. It has drawn numerous comparisons to Polish director Krzysztof Kieślowski's 1987 film Blind Chance, the outcome of which also hinges on whether the protagonist catches a train.
