Nightmare Theatre Season 4: Episode Guide & Ratings

The NMT gang return with the fully restored version of what may be the worst film ever made, as Sapo starts a manservant school and the Baron becomes a hotelier - with Torgo's help.

It's a double dose of Corman as brothers Roger and Gene conspire to tell the story of an astronaut infected with alien embryos bent on conquering humanity in this 1958 cheapie. Meanwhile, it appears that Mittens may be "in the (alien) family way" himself.

It's armageddon Italian style in this lurid tale of a post-apocalyptic dystopia ruled by homicidal bikers, released on an unsuspecting public in 1983. Back in the NMTV studios, the Baron and Sapo speculate on the snacks that might be available following a nuclear holocaust.

Sapo challenges the Baron to find the movie this time, and he comes back with the F.W. Murnau silent classic, with soundtrack provided by dream-prog legends Analog Missionary. Adding to his humiliation, Sapo's parents pay the NMTV studios a visit.

Coming soon

A young psychiatric nurse joins the staff at a remote mental hospital and gets more than she bargained for in this 1973 "video nasty". Back at the NMTV studios, Sapo imagines he is being haunted by a mysterious figure from his past.

An impending invasion of Salamander men from the planet Kulimon summons the legendary superhero Starman to planet Earth's rescue in this 1965 film cobbled together from episodes of the Japanese children's TV series.

Something is terrorizing the residents of some unnamed swamp town in this slimy 1959 sleezefest from the Brothers Corman. Back in the NMTV studios, Sapo goes on strike in protest of his failure to win Employee of the Year for the 125th time.

This 1974 shlocker, which ostensibly is about a group of college students on a Yeti-hunting expedition that evolves into something far worse, inspires the Baron to dress Sapo up in an old bigfoot costume to pull off a Patterson-Gimlin scam - with sadly predictable results.

Hollywood bad boy Dennis Hopper stars as a young sailor who suspects his new girlfriend might be a siren (the Greek mythological kind, not the loud noisemaking kind) in this vaguely atmospheric 1961 film, as Sapo regales the Baron and Mittens with his reminiscences of his hippy days when he dated a mermaid. Allegedly.

Glenn Ford and a pre-"Hutch" David Soul star in this middling 1974 made-for-TV movie about an Air Force crew's encounter with a UFO, while Sapo and the Baron dissect conspiracy theories and start their own low-budget airline.

Up from the forbidden depths comes a tidal wave of inanity as a young American artist vacationing in Mexico is terrorized by the titular beast in this 1954 film, the first of producer Roger Corman's long and mostly cringeworthy career.

A jazz pianist is haunted by the ghost of his ex-girlfriend, whom he watched fall to her death on the eve of his wedding to another woman in this Bert I. Gordon sleezeball from 1960. Back at the NMTV studios, cable access investigative journalist Dr Lester W. Sinclair is convinced that Sapo is an escaped convict, and launches a campaign to bring him to justice.
