Hulu has an abundance of riches for movie lovers in August, even beyond the regular influx of new titles. Earlier this month, the streamer added one of this year's best horror titles, The Monkey, and the well-reviewed action comedy Copshop is arriving on August 11. Both of those are very good films, but the one Hulu movie that you have to watch in August is Sharp Corner, a psychological thriller by writer and director Jason Buxton based on a short story by Russell Wangersky.
