Non-Horror Crosses: Too numerous to list.
The Story: In 1888, during the events of Bram Stoker’s novel, events diverge and Dracula marries Queen Victoria, causing a major alteration in the socio-political world for the next 125 years and beyond.
Notes: This is a divergent timeline, but not a parallel universe. In my theory, a parallel universe is created at the dawn of time at the same time as the main universe and other parallel universes. They may evolve similarly, but they are separate. Meanwhile, each universe has a main timeline, and at each moment, there are an infinite number of divergent timelines created off of the main timeline. When thinking of divergent timelines, try picturing a fork in the road. Both paths lead in different directions, but they both start at the same point, and once were the same road. The Anno Dracula timeline has shown to be an alternate timeline of the main Horror Universe in several other entries in this reference guide. Because it’s a divergent timeline, the above horror crosses, though depicted in an alternate manner, should still count for inclusions in the Horror Universe. Some of the above crossed series are already in, and the others are brought in via this crossover series despite being an alternate timeline series. For the record, the complete Anno Dracula series (thus far) consists of Anno Dracula, the Bloody Red Baron: Anno Dracula 1918, Judgement of Tears: Anno Dracula 1959 (aka Dracula Cha Cha Cha), Coppola’s Dracula (from the Mammoth Book of Dracula), Castle in the Desert: Anno Dracula 1977, Andy Warhol’s Dracula: Anno Dracula 1978 - 1979 (from the Mammoth Book of Vampires), Who Dares Wins: Anno Dracula 1980, The Other Side of Midnight (from Vampire Sextette), You are the Wind Beneath My Wings: Anno Dracula 1984) and Johnny Alucard.
WEREWOLF OF LONDON (FILM)
Release Date: 1935 (Contemporary Setting)
Series: Werewolf of London
The Story: A famed wealthy botanist, Wilfred Glendon, is attacked by a werewolf after which he finds he has himself been transformed into a werewolf as well.
Notes: This film has several later crossovers which you will find if you continue reading. This film has been “non-cross” referenced in such films as She-Wolf of London, The Howling, and The Cabin in the Woods.
World War II--GRINDHOUSE--"Werewolf Women of the S.S."--FU MANCHU is the lead villain in this unmade movie shown in a faux trailer. Ivan adds: WEREWOLF WOMEN OF THE SS features a werewolf woman of the SS played by the lovely and talented Sybil Danning, who also played Stirba the Queen of Werewolves in Howling II: Stirba - Werewolf Bitch. Not to push the same actor theory, I think it's safe to assume that Sybill was chosen for the WWOTSS role strictly because she was Stirba, so the conflation is justified. FYI, Howling II (1984) took place in 80 or 81 (I use 81, but there is more support for 1980).
THE HOWLING (FILM)
Release Date: 1981 (Contemporary Setting)
Series: The Howling
Horror Crosses: Gremlins; Bucket of Blood
The Story: To heal from psychological trauma she experienced, a television journalist goes to a secluded spa and encounters werewolves.
Notes: One of the colleagues of the main character is television journalist Lew Landers, who will appear again in Gremlins. Also appearing is Walter Paisley, played by Dick Miller. Miller first played Paisley in the film, Bucket of Blood, where he died, but either the rumors of his death were greatly exaggerated, or he was resurrected by unknown means. Or that film was a divergent timeline. I prefer the first explanation. Miller as Paisley reappeared in Chopping Mall, and has also appeared in Twilight Zone: the Movie and Hollywood Boulevard. This film is followed by several sequels, starting with Howling II: ...Your Sister is a Werewolf. It has been referenced as fictional or in homage several times in film and on television. It has been spoofed in Monster in the Closet, Dexter’s Laboratory, and Futurama.
Release Date: June 8, 1984
Horror Crosses: The Howling
Non-Horror Crosses: The Time Machine; Forbidden Planet; It’s a Wonderful Life; The Goonies
The Story: A father brings home an unusual gift for his young adult son. It’s a creature called a Mogwai, which he names Gizmo. Everything is fine, until he first gets the creature wet, which causes him to duplicate. But while Gizmo is cute and sweet, the others are not so. They then trick their owner into feeding them after midnight, a big no-no which transforms them into much deadlier creatures.
Notes: The main character’s father attends an inventor’s convention where the famous time machine from H.G. Wells’ The Time Machine is seen, and then a moment later, it’s gone, replaced by a puff of smoke. Robby the Robot from Forbidden Planet is also seen. If this is truly Robby the Robot, then likely he arrived with the time machine, and that would mean that Forbidden Planet occurs in one of the possible alternative futures of the Horror Universe. Television journalist Lew Landers also appears, who was last seen in the Howling. This story takes place in Kingston Falls, but if you pay attention to the background, it’s clear this is Bedford Falls from It’s a Wonderful Life. Perhaps at some point in the past 40 years, the town changed its name. Of course to complicate matters, the Christmas classic is shown on TV near the beginning of the film. But it could be that a film was made of George Bailey’s life. This film is followed by a sequel in 1990. A remake is in development at the time of this writing. This film has been referenced as fiction, paid tribute to in homage, and spoofed several times in other films and on television. Another crossover with this film happens in the Goonies. When Chunk tries to tell the police about the criminals of the film, the cop dismisses him, and recalls the time Chunk called them about the creatures that multiply in water.
Howling IV: The Original Nightmare (1988) (Video)
Howling V: The Rebirth (1989)
Howling VI: The Freaks (1991) (Video)
Howling: New Moon Rising (1995) (Video)
THE HOWLING REBORN (FILM)
Release Date: October 18, 2011 (Contemporary Setting)
Non-Horror Crosses: Everything John Hughes has ever written
The Story: A teen is being harassed by his werewolf mother.
Notes: The story is set in Shermer, Illinois. Shermer is the setting for several John Hughes films from the 1980s, mostly teen comedy/dramas. John Hughes stated in an interview before his death that everything he’s ever written takes place in the same universe. This film follows Howling: New Moon Rising and is the final in the series at this writing.

The Story: A group of teens head out for a weekend in a cabin in the woods, not knowing that they have been chosen as sacrifices to an ancient deity in order to save the world from his wrath.
Notes: This film exposes the secret truth behind modern horror. Behind it all is a secret organization, chosen to sacrifice youth to ancient gods. All of the above named crossovers have been linked in this film, and revealed to be part of this secret conspiracy. Most of the crossovers above come from the monsters and artifacts contained in the facility. While some of the monsters and artifacts are clearly from certain films above, many are based on certain types of horror films, in which case I included the more well-known of these film types. I recommend the well-researched Cabin in the Woods Wiki for a more detailed listing of the monsters and their inspirations. Note that I included in the above crossovers some monsters that only appeared in the official novelization and the official Universal Theme Park attraction tie-in. With this film, I break one of my major rules of crossover connecting. Though some of the crosses are direct crosses, like Evil Dead and Left 4 Dead, most of them are only connected because the films represent the more well-known films of the trope from which a certain monster comes. Normally, I would not count something that is “like something from”, but there is dialogue within the film that makes me break my rule. In one scene, referring to the monsters, security officer Daniel Truman says “They’re like something from a nightmare.” Lin, a head scientist, responds, “No, they’re something nightmares are from.” She goes on to explain that these monsters are the creations of the Ancient Ones, having been around since the beginning, and different cultures have told stories that interpret them in different ways. Thus, in the instance of this film, “like” is enough because of the author’s intent. And thus my love/hate relationship with Joss Whedon, for expanding the Horror Universe dramatically but making me do a lot of work to write this entry. Note that this film ends with the start of an apocalypse, so the end must veer into a divergent timeline. We must presume in the main Horror Universe, the virgin shot the fool. And if you haven’t seen the movie, that last sentence probably seems very bizarre. This film has been referenced as fictional in South Park, The Cinema Snob, Scary Movie 5, and Doc of the Dead. It is also paid homage to in Red Dawn when Chris Hemsworth and his friends once more wind up in a cabin in the woods. The film has also been spoofed in Robot Chicken and Scary Movie 5.
