It is logical, and it seemed easy enough, to begin a discussion of The Cat and the Canary with a discussion of the history of “old dark house” mysteries — those movies where a disparate and largely shifty group of people convene upon a mysterious old mansion and find themselves embroiled in — and probably accused of — either a murder or a theft. Lots of skulking, staring, and clutching hands appearing from behind curtains or the doors of hidden passages ensues. From the silent era to the end of the 1930s, there was a dizzying number of “old dark house” films produced. They were cheap to make, easy to write, and demanded little from the production company or the audience. At their worst, old dark house mysteries were harmlessly entertaining. Often they were much better than that. The formula was so adaptable that it could be grafted onto pretty much any type of movie. Even established series like the Bulldog Drummond and Charlie Chan movies fell back from time to time on the old dark house motif. From horror to comedy to crime to thriller, it was easy to crank out an old dark house version of the genre and keep everyone at least moderately satisfied.
