DEAD OF NIGHT is considered a horror classic. The anthology film is made up of a series of small stories that have become tropes of the genre. Unlike other classics the stories have since been improved upon imitated, stolen and butchered so many times over the years that they have become cliché. You can see it's influence on shows like THE TWILIGHT ZONE and movies like MAGIC. One could say that its influence has lasted longer than its impact. However, the one element that hasn't been improved upon is how compelling the framework story is.
The framing story is simple — an architect, Walter Craig (Mervyn Johns, A CHRISTMAS CAROL) is called out to a country home on a job. When he arrives the house seems so familiar to him and when he meets the people inside he is struck with the fear that he has been dreaming this situation for years. His fears spur others to share their tales of encounters with the supernatural. Craig is convinced that during the course of the evening he will be driven mad. However, one of the guests is Dr. Van Straaten (Frederick Valk, BAD BLONDE), a skeptical psychiatrist, who sets up the battle of wits to convince Craig that there are not demons lurking in the shadows.
