Upside Down is a 2012 science fiction romance film directed by Juan Diego Solanas and starring Kirsten Dunst and Jim Sturgess. The film takes place in a world where there are two twinned worlds with different gravities: the lower world and the upper world. The two worlds are separated by a boundary that is heavily guarded, and the people in each world cannot interact with each other.
Adam (Sturgess), a young man from the poverty-stricken lower world, falls in love with Eden (Dunst), a girl from the wealthy upper world, during their childhood. However, their love is cut short when Eden falls from a tree and is presumed dead.
Ten years later, Adam discovers that Eden is alive and working in the upper world's largest corporation. He becomes obsessed with finding a way to reconnect with her across the gravitational divide, but the laws of physics and the prejudice of the upper world's residents stand in his way.
Adam begins working for the corporation and develops a formula that can temporarily neutralize gravity, allowing him to cross into the upper world. He begins a dangerous journey to reunite with Eden, but their love is not accepted by the upper world's authorities and they face constant danger.
The film features stunning visual effects that showcase the two worlds' contrasting environments, and explores themes of social inequality, prejudice, and the power of love. The soundtrack, composed by Benoît Charest, also received critical acclaim.
Overall, Upside Down is a unique and visually captivating film that offers a fresh take on the classic love story.
