"Excuse me, sir? Are you okay?" In addition to Sam Mendes' long-take 1917 movie coming up this fall, we have another thrilling one-long-take film to watch right now. Whiteout is an 10-minute short film directed by up-and-coming filmmaker Lance Edmands, and it's a single-take drama set on a snowy road. When a young couple encounters a strange old man wandering in a snowstorm, they must decide if he needs help, or if he has more sinister intentions. Starring David Call and Sarah Tihany, with Patrick M. Walsh. It's a seriously suspenseful thriller that will turn your stomach. Edmands states that is intentions are to ask tough questions: "But what happens when we let our fear overwhelm our empathy?" It's a very provocative short that makes you confront your own feelings in a situation like this, a bit like Ruben Östlund's Force Majeure. Thanks to Short of the Week for debuting this.
