The Exchange

Although the plot is completely different, the way this movie was directed reminded me a lot of Upstream Color. It's about alien beings who can travel between dimensions. The main character is a hybrid soldier who falls in love with a human woman. There are no space ships or anything like that. A watch seems to be the only device used. Switching between black & white and color is used as a storytelling device.

This is far from a conventional love story and it doesn't even fit that label. It is more about the interaction between characters. There are virtually no special effects but it doesn't need any. The director allows you to figure things out yourself and doesn't give you a lot of explanation.

If you like deep, cryptic movies like Upstream Color or Donnie Darko then you will probably like this.
