Silly Sci-Fi Horror Goodness
A Japanese sci-fi horror starring the likes of Sonny Chiba, Peggy Neal, and Franz Gruber,The Terror Beneath the Seais, admittedly, unremarkable among a sea of cheesy b-movies.
That said, it is still a fun romp that fits so well into thatso-bad-its-good categorythat it will still tickle the fancy of those seeking out purposely silly cinema. At the same time, having a legend like Sonny Chiba gives the movie an entertaining edge, especially when seeing him alongside the roughly designed fish-men.

The House on Haunted Hill (1959)
The House on Haunted Hill
An eccentric millionaire, Frederick Loren (Vincent Price), and his wife Annabelle invite five people to a haunted house party. The guests are offered $10,000 each under the condition of having to stay the night. As the night progresses, the five find themselves coming up against all manner of terrors, including ghosts and killers.The House on Haunted Hillwas also remade in 1999, following the same premise as the original.
A Classic B-Horror Movie
A campy classic highlighting the early rise of the b-movie,The House on Haunted Hillis one of the best movies by sensational director William Castle. A natural showman, Castle was also known for packing in extra ‘features’ into the theatrical experience withThe House on Haunted Hillusing the “Emergo” gimmick — a skeleton with glowing eyes that would fly over the audiences during certain scenes.
While one can’t recapture that theatrical experience, the movie still resonates with the intended shock and sensationalism intended on release. Much of this comes from Vincent Price’s performance, which is wonderfully macabre in both delivery and screen presence. The film may lack the scares for modern audiences, but it is still a wonderfully written and performed dark piece of cinematic history that should be watched at least once.

Claustrophobic Horror at its Best
A unique combination of gothic horrorand sci-fi,Horror Expresspresents a fascinating story of terror and paranoia. The movie also has several other elements that make it stand out, including the presence of iconic actors like Peter Cushing and Christopher Lee, giving memorable performances.

Terror in Brazil
Brazil’s first horror film caused quite a stir on release, making it a notable horror film in history worth checking out. On top of its importance in cinema, the movie boasts a memorable antagonist in “Coffin Joe,” a darkened figure who carries a wickedness that made director José Mojica Marins feared both off and on the screen.

Driller Killer (1979)
Part black comedy and part slasher,Driller Killerfollows a troubled artist-turned-murderer as he goes on a killing spree across New York using a drill as his weapon of choice. The movie would mark the feature film debut of director Abel Ferrara, who would go on to cult infamy with movies likeMs .45,Bad Lieutenant,andKing of New York.
A Gritty Slasher
Taking place in the urban landscape of New York,Driller Killerperfectly captures the grit of the era. This backdrop, combined with the unapologetic nature of its killer (Reno), gives the movie an authentic punk rock vibe.
If that was not reason enough to check it out, the film has proven to be highly influential with its disjointed editing style that blurred the line between reality and fantasy. It may be a bit bleak and lacking a plot, butDriller Killeris a must-watch for those looking for gritty chaos.

A Convincing Tale of Madness

Adding elements of surrealism and unique cinematography, the ’60s film feels pretty ahead of its time, and is arguably thebest psychological thrillerreleased in the era. Ultimately,Repulsionis a convincing tale of madness packed with suspense and mystery, making it an excellent film to dig deeper into on a solo watch.

Matters become further complicated when she learns that the woman she suspects is part of a conjoined twin (played by Margot Kidder), with each having drastically different personas. The more she becomes invested in the case, the more she is drawn into the insidious nature of the twins.
Two’s Company
Almost interchangeable with the previously mentionedRepulsion, Brian De Palma’sSistersalso deals with themes of madness brought on by fear of men.
At the same time, the movie alsoutilizes creative cinematographyto disorient the viewers and have them experience the same uncertainty and mental instability portrayed throughout, including the early use of split-screen as a narrative device. Still, the approach here is slightly more intense and the methods of the antagonist more malicious, giving this one a slight edge.

The movie would spawn three sequels, and act as inspiration for the absurdScanner Copand its sequel.
Director David Cronenberg, a master of body horror who crafted some of the most memorable horror movies of the ’80s fromThe FlytoVideodrome, hardly needs any introduction to fans of the genre.
Add in the fact thatScannersincludes one of the most iconic scenes in all the director’s filmography, the ‘head explosion’ scene, and this movie has cemented itself as a true classic. If you have been looking to check out David Cronenberg or revisit his ’80s work,Scannersis a welcome addition to free films on The Internet Archive.
