THE HISTORY OF HORROR

By 1950's technology had vastly improved, two sub-genres began to appear; Horror-of-armageddon  and Horror-of-the-demonic .A lot of productions featured humanity overcoming threats from "outside": alien invasions and deadly mutations to people, plants, and insects. In the case of some horror films from Japan, such as Godzilla (1954) and its sequels, mutation from the effects of nuclear radiation.

Some horror films during this period, such as The Thing from Another World (1951) and Don Sielgel's Invasion of the Body Snatchers (1956), managedd to use the paranoia from the Cold War for
scaring audiences.

Many of the special effects back then would seem quite primative to us nowadays, this was because computer generated effects were not availible for use in films, so instead models were made, good example of these are featured in the video above (Godzilla).
