Five men enter a train carriage in London bound for Bradley, and are joined by a sixth, the mysterious Doctor Schreck (Peter Cushing) whose name, he mentions, is German for "terror". During the journey, the doctor opens his pack of Tarot cards (which he calls his "House of Horrors") and proceeds to reveal the destinies of each of the travellers. This provides the framework to tell five horror stories.Peter Cushing - Dr. Schreck
Architect Jim Dawson (Neil McCallum) returns to his old family home on a Scottish isle to make renovations for the new owner, Mrs. Biddulph (Ursula Howells). Biddulph explains she bought the secluded house to help her recover from the death of her husband.
Dawson finds the coffin of Count Cosmo Valdemar behind a fake wall in the cellar. Valdemar, the original owner of the house, was killed in a conflict with the Dawson family centuries ago. Local legend states that Valdemar would reclaim his former home and take revenge on the current owner. Dawson discovers that Valdemar is rising at night as a werewolf, and has already killed a housemaid (Katy Wild).
Believing Mrs. Biddulph to be in danger, he makes silver bullets out of an ancestral cross that protected the house against Valdemar's spirit. When the wolf appears, Dawson is baffled that the bullets don't kill it. Mrs. Biddulph explains that she has replaced the silver bullets with ordinary ones. She reveals to Dawson that the truth of the legend is that Valdemar will take revenge on the last descendant of the Dawson clan, and placing a Dawson corpse in Valdemar's coffin will restore Valdemar to life in human form. It was all a trap: Biddulph is Valdemar's wife, who has returned from the grave after 200 years.Neil McCallum - Jim Dawson

Running from an unknown force, Castle's character stumbles against a wall where there is a garish poster for "Dr Terror's House of Horrors".

Pompous art critic Franklyn Marsh (Christopher Lee) seems more concerned with his own devastating wit than art itself. Painter Eric Landor (Michael Gough) bears the brunt of one of Marsh's tirades, but gets even by humiliating the critic publicly. When Landor takes it too far, Marsh responds by driving over him with his car, causing Landor to lose one of his hands. Unable to paint any more, Landor commits suicide.

The frame story ends with a twist. Dr. Schreck informs the men that the only way they can avoid these horrible destinies is by dying first. When the train stops, the men find out that they are already dead, having perished in a train wreck while their fortunes were being told. Schreck is revealed to be Death himself.
The film was a conscious attempt by Milton Subotsky to repeat the success of Dead of Night (1945). Subotsky considered that movie to be "the greatest horror film ever," and used it as a blueprint for Dr. Terror and the rest of Amicus's portmanteau films. The script began as a stillborn television series in 1948 during the time when Dead of Night was a recent release. Subotsky wrote the original stories in 1948 when he was employed as a scriptwriter for NBC's Lights Out series.
Filming began on Dr. Terror's House of Horrors at Shepperton Studios on 25 May 1964 with a budget of £105,000 and was completed on 3 July 1964. It was released on 5 February 1965.
Donald Sutherland was paid ₤1,000 for his performance.
Dr Terror's House of Horrors was filmed using the cinematic process known as Techniscope.
