I saw this movie maybe two or three years ago, but I saw it on a streaming website so I don’t know how old it is. It was in color and in english, and the main thing I remember from this movie is a scene near the end set in some sort of small diner in the middle of nowhere. The main characters (I believe its two couples) are gathered at a booth and a group of people walk in and they all are talking to eachother about whatever has happened up to this point, but suddenly one of the people who walked into the diner kills one of the main characters sitting at the booth, and the other people grab and hold the others sitting at the booth so they are unable to do anything but watch their friend get killed.
I’m fairly sure the movie was roughly similar in premise to the movie “The Game”, but I can’t for the life of me remember any other scenes definitively! It’s driving me nuts!
The Killing Jar?
