Trivia

* During filming, Kenny Everett would often forget that his character walks with a limp, or limp with the wrong leg. Director Ray Cameron eventually had to stick signs up on the set that said 'Limp!' and had a clapper boy charged with reminding Kenny to limp before each scene.
* Despite being third billed, Vincent Price only has five scenes.
* When Michael McIntyre (son of director Ray Cameron) met Billy Connolly (husband of Pamela Stephenson), Michael brought up this film. To which Billy simply responded "Pamela's been in a lot of shit movies."
* International star Vincent Price was visually emphasized on the American home video front cover sleeves in the USA due to British comedian Kenny Everett not being very well known outside of England and the UK.
* Director Ray Cameron's son Michael McIntyre voiced E.T. at the end of the film when he was 6 years old.
* Kenny Everett's successful move from Thames television to the BBC led his head writers Barry Cryer and Ray Cameron being offered various new projects, the first of which came to fruition was this film. It remains the only cinema feature to be directed by Ray Cameron.
* First, final and only ever movie role in a theatrical feature film of television comedian Kenny Everett.
* Headstone Manor was portrayed by *Northaw Place* in Northaw and Cuffley, Hertfordshire, England, UK.
* Final Vincent Price theatrical film to feature the word *house* in the title. Price throughout his career appeared in nine horror movies with the word "house" in the title. These were [in order]: The House of the Seven Gables (1940), House of Wax (1953), House on Haunted Hill (1959), The Fall of the House of Usher (1960), House of a Thousand Dolls (1967), The Hilarious House of Frightenstein (1971), Madhouse (1974), House of the Long Shadows (1983) and Bloodbath at the House of Death (1984).
* The only ever theatrical feature film written by Ray Cameron and Barry Cryer.
* The film was originally rated with an 18+ certificate by the BBFC when released in UK cinemas. It has now been given a 15+ certificate when it was released on DVD in 2008.
* Executive Producer Laurence Myers later said of this movie in an interview with Phelim O'Neill published in the 22nd August 2008 issue of the 'The Guardian' UK newspaper: "It's a fairly terrible film. I recall showing it to BBFC censor and secretary James Ferman, who thought it was fine and funny enough, but thought we were showing him the reels in the wrong order. We weren't. The film just doesn't make sense."
* According to the 'EOFFTV Review' website, co-stars Vincent Price and Kenny Everett *...supposedly had a mutual friend in Frankie Howard who persuaded...[Price]...to take the part*.
* Apparently, the movie has never been released in Italy. Given the country's creation of the *giallo* genre and the horror films of Mario Bava, Lucio Fulci and Dario Argento, this seems curious as to the reason(s) why.
* Then actress Pamela Stephenson portrayed a character called Doctor Barbara Coyle. In real life, Stephenson later became an academic and garnered a Doctor in Psychology qualification receiving her PhD in 1996. She also previously had starred in the Australian comedy film 'Doctors and Nurses' (1981).
* The movie's plot was *nicked* from 'The Haunting' (1963) according to a review at the 'GoodReads' website.
* The movie's opening title cards read in order: *August 12th 1975* - *Thursday* - *Give or take a day*.
* Cast members Gareth Hunt and Pamela Stephenson had both previously appeared about seven years earlier in the 'Angels of Death' (1977) episode of the British television series *The New Avengers* (1976-1977). Both of the productions featured the word *death* in their titles.
* The former German name of Dr. Lukas Mandeville (Kenny Everett), when he was previously practicing as a surgeon in Germany, was Dr. Ludwig Mannheim.
* The print masters of the film were lost prior to the movie being released on DVD in 2008. Marc Morris of Nucleus Film, an independent London based DVD company, said in an article published in 'The Guardian' newspaper on 22nd August 2008: There were no prints of 'Bloodbath' ['at the House of Death'] to be found and it wasn't even sold to television so we had nothing to fall back on. The original negative had to be found." The story added: In the vaults, *...'Bloodbath' had accrued around £25,000 in overdue charges, and for a film with such limited marketability that price tag could have scuppered the whole endeavour. Fortunately, Morris was able to haggle the amount down to a much more manageable figure when the lab realised that whatever he was offering would be the only money they'd ever see from the movie. Morris's offer was better than nothing, even if it was only marginally so. As a result, a near-pristine negative has been saved from destruction and the DVD of 'Bloodbath' has a picture quality to rival its competitors on the shelves.*
* A novelization of the film, *Bloodbath at the House of Death: A Novel* (1984), was authored by Martin Noble and first published by book publisher Star in the film's first release year as a movie-tie with the picture's theatrical season. According to the 'Wikipedia' website, this novel *named Marcel Wave (one of Kenny Everett's TV characters) as the resident who underwent spontaneous combustion.*
* The age of the Satanic priest the Sinister Man (Vincent Price) was 700 years.
* In pre-production, the picture almost fell over from the funding and financing failing to be provided, and executive producer Laurence Myers stepped in and saved the film from going into turnaround and back into development hell.
* According to an article published in 'The Guardian' newspaper on 22nd August 2008, *the production coincided with the aftermath of Kenny Everett's infamous 'Let's bomb Russia! ... Let's kick Michael Foot's stick away!' outburst at the Young Conservatives' annual conference, so the film's title was regularly invoked in the press. Although his conference appearance did little damage to Everett's popularity with his fans, the media turned on him. The knives were out and well sharpened by the time 'Bloodbath' came out, and its vitriolic critical reception still taints the film's reputation.*
* The closing credits state: *The producers wish to thank Ian Rowley for his assistance on special effects.*
* The name of the ritual ceremony performed by the Satanic worshipers was the *Night of Blood*.
* The movie's closing credits state: *Renault cars supplied by courtesy of Vince Maishman of Stations Supreme Potters Bar*.
* In one sense, this was actually the second and not the first Kenny Everett movie. Screenwriters Barry Cryer and Ray Cameron had previously written Kremmen: The Movie (1980) which had starred Everett who voiced the title character. However, this was actually a compilation of all the Captain Kremmen segments from Kenny Everett's television show and its running time only amounted to 24 minutes which is not long enough to qualify as a feature film, though nonetheless, it was still the first Kenny Everett *movie* in a sense, even if it was a short film. Moreover, prior to 'Bloodbath at the House of Death' (1984), Everett starred in two specially made-for-video comedy features. They were 'The Kenny Everett Naughty Joke Box' (1981) and 'The New Kenny Everett Naughty Video' (1982).
* The movie features the phrase *paranormal activity* said by a character. This was about twenty-three years before the famous film franchise began with 'Paranormal Activity' (2007).
* The film was *loosely inspired* by 'The Amityville Horror' (1979) according to the 'Wikipedia' website.
* The name of the countryside pub was the *Duck & Pullet* Inn. It had a double meaning just as *The Old Cock Inn* had done in 'Carry on Dick' (1974) which had been made and first released about exactly a decade earlier. That year, Vincent Price was seen in the horror movie 'Madhouse' (1974) with this picture also featuring the word *house* in the title like 'Bloodbath at the House of Death' (1984).

## Cameo

* Barry Cryer: The co-screenwriter in a brief cameo early in the film as a police inspector.
* Michael McIntyre: Uncredited, the then about eight year old son of the film's director Ray Cameron, as the voice of E.T. He later when grown up became a comedian in England. This voice cameo appearance was first publicly revealed in his autobiography *Life & Laughing: My Story* (2010) which was about twenty-six years after the movie had first come out.

## Director Cameo

* Ray Cameron: The film's director in a minor cameo as a policeman.

## Spoilers

* Body Count: 18. The eighteen deaths from the 1975 bloodbath were, as detailed in the film, as follows: One was hanged, one was blown-up, two were axe-murdered, two had their throats slit, two were struck by lightning, four people were skewered in the same bed, and six were found in a deep freezer wrapped in cling wrap after having been shot.
* In Scary Movie 2 (2001), the scene of Tori Spelling and a ghost having intercourse and then smoking in bed afterwards, is a homage to a similar scene in this British movie "Bloodbath at the House of Death" (1984) which is also about a group of scientists investigating a haunted manor. In both movies, a blonde is sexually attacked by an invisible ghost in her room, but then starts to enjoy it. Afterwards, she is shown lying on the bed smoking a cigarette while the invisible ghost's cigarette is seen floating beside to her. In both films, the woman gets upset when the ghost leaves her.
* The movie's closing title card read: *The End. Or is it the Beginning?*.

## Goofs

### Continuity

* When the spaceship is taking off, it is night. But when E.T. is trying to catch up with the ship, it is day.
* A Monk enters the toilet, at the beginning of the onslaught, with an short handled axe and leaves with a large bladed knife.

### Factual errors

* The title cards at the start state that 12 August 1975 was a Thursday. It was actually a Tuesday.
The title card that follows the one stating it was a Thursday proclaims "Give or take a couple of days" which, if that date was in fact a Tuesday, is perfectly correct.
