12 Angry Men

They actually aren't all angry, but this makes for a better title. I read the play back in eighth grade and finally got around to watching the movie. It's about a group of jurors charged with finding an 18-year-old guilty or innocent of the murder of his father. Wonderful acting, dialogue, characters, and suspenseful buildups, along with some very strong visuals (watch how the camera pans for long periods, rather than modern techniques of cutting back-and-forth between characters). A fascinating take on what takes place in a jury room and in the mind of jurors. 12 angry men
