Another timely Halloween release (and another completely awesome Criterion cover- these guys really know what they're doing), this movie has the distinction of being one of the earliest serious takes on the "haunted house" genre. It's a genuine ghost story, one of the very first, even though there'd been plenty of monster movies before (Frankenstein, Dracula, etc.). Ray Milland and Ruth Hussey play a pair of siblings who movie into a creepy old English mansion with, you guessed it, a shady past. Perfect time to check this out.
