Sci-Fi Movies

Sci-fi films are often quasi-scientific, visionary and imaginative - complete with heroes, aliens, distant planets, impossible quests, improbable settings, fantastic places, great dark and shadowy villains, futuristic technology, unknown and unknowable forces, and extraordinary monsters ('things or creatures from space'), either created by mad scientists or by nuclear havoc. They are sometimes an offshoot of fantasy films (or superhero films), or they share some similarities with action/adventure films. Science fiction often expresses the potential of technology to destroy humankind and easily overlaps with horror films, particularly when technology or alien life forms become malevolent, as in the "Atomic Age" of sci-fi films in the 1950s.
