World Without End

The first US time machine film from 1956 is a fun but clunky Technicolor adventure. Astronauts accidentally travel 500 years into the future, where the meek, pacifist human survivors hide from barbaric mutants in an underground civilisation. 5/10

Forbidden Planet

Based on Shakespeare, MGM’s 1956 epic starring Anne Francis & Leslie Nielsen is a landmark SF movie. The pulpy premise of space explorers saving a virgin from an alien monster hides surprisingly serious and adult themes. 9/10

Invaders from Mars

This 1953 classic is the most visually unabashed SF movie of the 50s. While hampered by a low budget, this first “invasion of the body snatchers” film scared a generation of kids witless, but also contains interesting themes for adults to chew on. 7/10

Captive Women

Christian mutants and Satanist “norms” must unite against evil marauders in the nuclear-scarred ruins of New York in this 1952 curio set in 3000 A.D. A good cast and an interesting idea butt heads with a clunky script and an inexperienced director. 4/10

Flight to Mars

The first team of explorers to Mars are welcomed and double-crossed by a Martian civilisation attempting to hijack their rocket and invade Earth. A 1951 low-budget effort by Monogram, the movie’s striking for its visuals, but badly scripted and routinely directed. 5/10.

Unknown world

Preparing for a potential nuclear winter, a team of scientists test the theory that the Earth is hollow, in this 1951 cheapo from visual effects wizards Jack Rabin and Irving Block. Loosely based on Verne and Burroughs, Unknown World has the makings of a good film, but stumbles in all departments. 4/10.
