Film / Sliding Doors

Helen Quilley (Gwyneth Paltrow) just got fired. And now she missed the tube train, too. Some kid was in her way, slowing her down for a second.

But wait! She didn't miss the tube! The mother of the kid pulled the kid away, so Helen was never slowed down.

The Helen who got on the tube meets an interesting guy on the tube, and when she gets home she catches her boyfriend cheating. She breaks up and gets an Important Haircut, turning blonde.

The Helen who missed the tube gets robbed, and comes home to be comforted by a boyfriend who had more time to cover his tracks a bit. She keeps her old hairstyle and remains brunette.

As time goes by, blonde Helen and brunette Helen live increasingly different lives. And yet they seem to somehow remember each other, each of them getting a sense of déjà vu when encountering something that is important in the counterpart's life.

This film provides examples of:

  • Alternate Self: Blonde Helen and brunette Helen.
  • Alternate Timeline: Two time lines - one where Helen got to the tube and one where she didn't.
  • As You Know: Gerry's pal Russell spouts some exposition, to which Gerry repeatedly replies "I know!"
  • Bitch Alert: Lydia's Establishing Character Moment is full of this.
  • Expository Hairstyle Change: Without the difference in haircut, it would be hard to tell the two time lines apart.
  • Flash Sideways: Each Helen instinctively picks up on things important to the other Helen.
  • Flatline: Used to show when one of the characters dies in one of the timelines.
  • For Want of a Nail: A kid getting in her way for a second, making the difference between two radically different lives.
  • Foreign Remake: The storyline recycles in a Lighter and Fluffier way the plot of an earlier film, Blind Chance.
  • Girlish Pigtails: Helen, when she has to work as a sandwich delivery girl and waitress.
  • Green-Eyed Monster: Lydia is this.
  • Hard-Drinking Party Girl: Anna. Gerry nearly gets away with the extra wine glass in the laundry basket (left by Lydia) suggesting Anna left it there at one of their house parties. Anna admits it's something she'd probably do.
  • Important Haircut: The change in hairstyle signifies a change in lifestyle.
  • In Spite of a Nail: Helen met James. Helen lost her unborn child. Gerry has impregnated Lydia. Helen has found out about Gerry and Lydia and has left Gerry. Which time line am I talking about? It's worth noting that all of those things come true in very different ways and at different times, however.
  • Ironic Echo: In the first time line when James and Helen meet he says "Cheer up, you know what the Monty Python boys say", and Helen replies "Always look on the bright side of life?" James then corrects her with "No one expects the Spanish Inquisition." When they meet again in the next time line he says the same thing and Helen responds with the latter line this time.
  • Kick the Dog: Lydia, who not only makes up a case of food poisoning just so she can harass Helen, but also pretends she's interested in hiring her, just so Helen will show up at her apartment while Gerry is there so she can reveal Gerry's unfaithfulness to her in the cruelest way possible.
  • Life Will Kill You: One of the main characters is just standing there, having what would have perhaps been the most important conversation in a long and happy life. Suddenly a car runs over her. Downer Ending in one time line, but it is indicated that the trauma of her own death helps her to get a happy ending in the other time line.
  • Love Transcends Space Time: Two time lines, two lives, one romance.
  • The London Underground: The plot diverges at the main character catching / missing her train at Embankment station, setting off events for the rest of the film (which shows us two parallel lives from that point on). The actual scenes underground were filmed on the Waterloo and City Line.
  • Manic Pixie Dream Girl: Gender reversed. James is the Manic Pixie Dream Guy for Helen as he helps her to loosen up and enjoy her life, doing kind of silly things. And encourages her to start her own business when she is fired.
  • Mirror Monologue:
    • Lampshaded after Gerry almost had his "secret romance" revealed to his live-in girlfriend:
    Gerry [looking in the mirror]: You have two head problems. One, that was close, very close. Put in layman's terms, she nearly caught you. Two, and this is far more worrying than the first one, you're talking to yourself in the mirror again. Really bad sign.
    • Later brought up again by his friend:
      Russell: You've been talking to yourself in the mirror again, haven't you?
  • Missed the Bus: The plot is based on the difference it makes to this woman's life whether she gets or misses a tube train.
  • Plot-Inciting Infidelity: While the two timelines split with Helen missing the titular doors, the more important catalyst for divergence is when the Helen who caught the train walks in on her boyfriend cheating on her.
  • Service Sector Stereotypes: The worse-off scenario had the heroine fired from her job to become a waitress / delivery girl for a sandwich bar, much to the delight of her boyfriend's "other woman", who revels in exploiting and insulting her, knowing that her rival can't fight back.
  • Shout-Out: Serious Beatles fans surely took notice when Helen and Anna direct the taxi driver to take them to "Number 9, Menlove Avenue". Menlove Avenue was the street in Liverpool where John Lennon lived for most of his childhood, and he had a thing for the number nine.
  • Unusually Uninteresting Sight: Helen uses this for effect when she walks in on Gerry with Lydia. The first thing she remarks on is not the fact he's in bed with another woman, but instead the fact that she didn't think he liked Elton John.
  • We All Live in America: A small case but Helen and Anna reference Jeopardy!, an American game show which does air on some channels in the UK but is unlikely to be talked about casually by two British women.
