The Monster Club is a 1981 British anthology horror film directed by Roy Ward Baker and starring Vincent Price and John Carradine. It is based on the works of the British horror author R. Chetwynd-Hayes. It was the final film from Milton Subotsky, who was best known for his work with Amicus Productions; Amicus were well known for their anthologies, but this was not an Amicus film. It was also the final feature film directed by Baker.

A fictionalised version of author R. Chetwynd-Hayes is approached on a city street by a strange man who turns out to be a starving vampire named Erasmus. Erasmus bites the writer, and in gratitude for the small "donation", takes his (basically unharmed but bewildered) victim to the titular club, which is a covert gathering place for a multitude of supernatural creatures. In between the club's unique music and dance performances, Erasmus introduces three stories about his fellow creatures of the night.

A young, financially struggling woman takes a job at a secluded manor house owned by Raven, a hybrid creature called a Shadmock, who leads a troubled and tragic existence and is notorious for its demonic whistle. As time goes by, the girl, Angela, develops a friendship with the mysterious Shadmock, and he eventually proposes to her. Alarmed, Angela refuses, but her controlling boyfriend forces her to go through with it to gain the Shadmock's vast wealth. On the night of the engagement party, Angela is caught robbing the Shadmock's safe and screams that she could never love him. Heartbroken, the Shadmock whistles and destroys Angela's face. Her boyfriend is driven insane and locked away in an asylum upon seeing her.

The timid son of a peaceable family of vampires lives a miserable, lonely life where he is bullied at school and his father spends little time with him. The son discovers his father is a vampire, being relentlessly hunted by a team of bureaucratic undead-killers, The Blini or B-Squad, led by Pickering. The hunters break into the house and stake the vampire father, but the tables are turned when the father bites Pickering, meaning that he will now have to be staked by his own assistants. A chase ensues, and Pickering is staked. After his men take his body away, the timid son and his mother return to the basement to find that the father faked his death using a stake-proof vest filled with tomato ketchup.

A movie director scouting locations for his next film pays a horrifying visit to an isolated, decrepit village, Loughville, where the sinister residents refuse to let him leave. He discovers to his horror that the village is inhabited by species of corpse-eating demons called ghouls who unearth graves for food and clothes. And now there are no more graves to plunder, and the ghouls are hungry for flesh. While imprisoned by the ghouls, he meets Luna, the daughter of a ghoul father and a deceased human mother, making her a Humegoo. Luna advises him to hide in the church, as ghouls cannot cross holy ground. Whilst in the church, the director discovers the terrifying truth of Loughville; centuries before, a swarm of ghouls invaded the village, mated with the humans, and made their nest there. With the aid of Luna, the director attempts to escape and almost succeeds – only for Luna to be killed by the ghouls and the director captured again and returned to the village by ghoul policemen.

At the end of the film, Erasmus cheerfully lists to the other club members all the imaginative ways that humans have of being horrible to each other and declares that humans are the most despicable monsters of all. Thus Chetwynd-Hayes is made an honorary monster and member of the club.

Christopher Lee was originally sought for the role of Chetwynd-Hayes, but flatly turned the offer down simply upon hearing the film's title from his agent. Peter Cushing also turned down a role, though he would soon work with director Baker on the TV film The Masks of Death. It was one of the last feature films for Anthony Steel.
