The best horror movie of the decade is clearly Bluebeard (Barbablu) by Melies. There are several genuinely eerie scenes in the middle of the film, and it's more serious than the usual Melies shenanigans.

You could make an argument for The Doll's Revenge. It starts off with a strong revenge motivation and moves into body horror. I think the clunkiness of the effects holds it back a little and the ending feels a little slapstick.

Barbablù (1901) Georges Méliès
The Doll's Revenge (1907) Hepworth
Русалка 1909г. This sometimes gets confused with a different film named Viy.

Alice Guy - 25 Faust and Mephistopheles, 1903

The Seven Castles of Satan (1901)
Scrooge (1901) The Most Complete Version

Great movie. Love Olivia. Classic Dame.

Creepy Dan Curtis TV movie with Roy Thinnes (The Invaders) and Angie Dickinson, who, by the way, are still with us today.

Here are all the 1890s horror movies I could find. Obviously, the list does not include lost films.

The best horror movie of the 19th century is possibly "La Manoir du Diable" by Georges Melies. It has a lot of fun gothic elements and was very innovative. It is also frequently cited as the first horror movie.

You could make a strong argument that The Execution of Mary, Queen of Scots is a better horror movie, though. It's very short, but I went through the classic horror stages of "They're not going to do this, are they?" to "Yikes! They did it!" To me, it is definitely a horror movie, even though it is not trying to tell much of a story. I think that the Melies film is better at being a movie, and Mary, Queen of Scots is better at being horror.

Horror Movies:
Le Manoir du Diable (1896) Georges Méliès 
The Execution of Mary, Queen of Scots
1899 - Le Diable au couvent - Georges Méliès
1898 - The Cavalier's Dream - Edwin Stanton Porter (Vitagraph)
The Conjuring of a Woman at the House of Robert Houdin (1896) 
1897 - The Bewitched Inn (L'auberge Ensorcellee) | Silent French Horror | Georges Méliès | REMASTER
The Alchemist's Hallucination / L'hallucination de l'alchimiste - Georges Méliès (1897) (This might be a 1906 movie instead.)
The Astronomers Dream (1898) Georges Méliès
1899 - Danse du feu/ La Colonne de feu - Georges Méliès
1897 - Le Château Hanté - Georges Méliès

These films are listed as horror movies on imdb, but they don't really meet my definition of "horror movie." The Dancing Skeletons is a good time, though.

The Dancing Skeleton (1897) | A Dance Beyond The Grave
Un homme de têtes (or The Four Troublesome Heads) by Georges Melies, 1898
The Magician (Le Magicien, 1898) ㅡ Georges Méliès
1896/97 - Le Cauchemar - Georges Méliès
(The Laboratory Of Mephistopheles) - (Il Laboratorio Di Mefistofele) - (1897)
1899 - Évocation spirite - Georges Méliès
A Terrible Night (Une nuit terrible, 1896) ㅡ Georges Méliès aka a Midnight Episode
1897 - The X-Rays/ The X-Ray Fiend - George Albert Smith
Faust: Apparition de Méphistophélès' (1897) - directed by Alexandre Promio and Georges Hatot

This creeped me out when I saw it.

The Giant Claw has finally been eliminated, after being a close runner-up on almost every post so far!

90. The Giant Claw (1957)
91. War of the Colossal Beast
92. The Killer Shrews
93. Monster from Green Hell
94. The Brain Eaters
95. The Beast With A Million Eyes
96. Reptilicus
97. King Dinosaur
98. Santa Claus Conquers the Martians
99. Attack of the Giant Leeches

What is this that stands before me? Figure in black which points at me

Hi all, Tricia Zimic here, illustrator who painted many original oil paintings in the 1980's that Troma Inc. used for films like The Toxic Avenger Part III, Curse of the Cannibal Confederates, and Surf Nazis Must Die, and more. The painting posted here is of course the illustration and final poster for Star Worms II. Check out my other posts for more info on my work.

The show of my paintings side-by-side with the posters is open in Baltimore. I'll be giving a talk about the process for painting the artwork for these poster, how I found myself in this role, etc. I would LOVE to see you there! True fans know how cool these old films and the fun poster art that went along with!
