When a crew of scientists returns from Mars with a sample of the space spores that contaminated their ship, they inadvertently bring about a nightmarish earth invasion. After one of the spores is analyzed in a lab, it escapes, eventually growing into an enormous, rampaging beaked beast. An intergalactic monster movie from longtime Shochiku stable director Kazui Nihonmatsu, The X from Outer Space was the first in the studio’s short but memorable cycle of horror pictures.

After an airplane is forced to crash-land in a remote area, its passengers find themselves face-to-face with an alien force that wants to possess them body and soul—and perhaps take over the entire human race. Filled with creatively repulsive effects—including a very invasive bloblike life-form—Hajime Sato’s Goke, Body Snatcher from Hell is a pulpy, apocalyptic gross-out.

In this atmospheric tale of revenge from beyond the watery grave, a pirate-ransacked freighter’s violent past comes back to haunt a young woman living in a seaside town. Mixing elements of kaidan (ghost stories), doppelgänger thrillers, and mad-scientist movies, Hiroshi Matsuno’s The Living Skeleton is a wild and eerie work, with beautiful widescreen, black-and-white cinematography.

The insects are taking over in this nasty piece of disaster horror directed by Kazui Nihonmatsu. A group of military personnel transporting a hydrogen bomb are left to figure out how and why swarms of killer bugs took down their plane; the answer is more deliriously nihilistic—and convoluted—than you could imagine. Also known as War of the Insects, Genocide enacts a cracked doomsday scenario like no other.
