A guy in Poland had his girlfriend go to the movies with her friends, and arranged for one of the previews to be a fake trailer that he made. He used clips from "The Borne Ultimatum" and the Liam Neeson movie "The Grey". And at the end, it showed him walking through the front door of the building, and then into the theater she was sitting in. He also set up a camera inside. So the video he posted online has picture-in-picture, and you get to see her reactions to everything. She realizes something's up when she sees a picture of herself at :26. He arrives to propose at 2:41. Nothing after that is in English, but he gets down on one knee at 3:21.
