Adam and Eden, the hero and heroine of French film “Upside Down” are star-crossed lovers, the poor boy and the rich girl. Just like Romeo and Juliet, Laura and Alec or Megashark and Giant Octopus, they live in different worlds – no, they literally live in different worlds, one suspended above the other and each with its’ own gravity.
When Adam (Jim Sturgess) last saw Eden (Kirsten Dunst) she was falling upwards towards her own world and to her death. Years later, when Adam discovers that Eden is still alive and working for Transcorp, a mysterious company whose offices link the two worlds, he comes up with a crazy plan to win her back.
Adam and Eden strive to escape the limitations of their societies and geometries, so Upside Down is Science Fiction.
“Upside Down” tells a simple and rather traditional story of love across the class divide, with a crude and obvious use of metaphor. Good performances from Sturgess and Dunst can’t cover over the lack of depth in the writing. I don’t care. Like Tron: Legacy, Mad Max: Fury Road and Daybreakers, this film is an example of near-perfect worldbuilding. It would work with or without the humans, although arguably any film where Kirsten Dunst kisses someone upside down is by definition a good film. The genius of “Upside Down” is the extraordinary environment of the twin worlds. It's thought out, designed and filmed in a way that every scene is visually striking, and every detail of every scene tells a chapter of the story, the history of the characters and their societies - a story far more rich and nuanced than the melodramatic script.
