Red Riding 1974 (2009)

Red Riding 1974 opens the British crime trilogy based on David Peace's novels, following a journalist digging into corruption and murder tied to Yorkshire in the 1970s. Michelle Dockery appears in the cast, well before her Downton Abbey years, and the archive holds 1 scene of her nude on screen here. It's a rare piece of her filmography for anyone used to seeing her in period corsets rather than exposed.
