Alien Invasion

Warning from Space

Friendly star-shaped aliens try to warn Tokyo’s inhabitants of a planetary collision. Humans flee in fear at the sight of the alien starfish, so one of them shape-shifts and infiltrates. This 1956 colour spectacle is entertaining but contrived. 5/10

This Island Earth

With a more adult angle than most fifties SF movies, Universal’s 1955 big-budget splash dazzles both with wonderful visuals and clever ideas. That the screenplay mismanages these ideas prevents its inclusion with the bona fide classics. 7/10

Target Earth

One of the first “empty city” movies, this 1954 low-budget clunker starring SF legend Richard Denning has all the trappings of a taut, character-driven SF classic. Unfortunately the hackneyed script does away with much of its potential. 4/10

Killers from Space

Famous for its villains with ping pong ball eyes, this 1953 low-budget entry sees Peter Graves abducted by aliens planning to invade the Earth. Sadly, the stale script isn’t nearly as fun as the design of the antagonists would suggest. 2/10

The Quatermass Experiment

Hugely influential, BBC’s 1953 mini-series about an alien virus mutating their hosts was a massive British TV event. Aired live, its sets were clunky and the acting stiff, but the great script and innovative direction overcome the flaws even today. 6/10

Robot Monster

Shot on 16,000 USD in 1953, this cult classic is as inept as it is unique. Told as a boy’s surreal nightmare, it features an alien robot gorilla in a diving helmet experiencing an existential crisis as he is about to wipe out the last six people on Earth. And soap bubbles. 7/10

It Came from Outer Space

Ray Bradbury’s story is poetically put on screen in this 1953 classic. Richard Carlson stars as a mediator between body-snatching aliens and gun-happy townsfolk. Intelligent, well-filmed and thoughtful, it may be too slow for some tastes. 8/10

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

The War of the Worlds

An everlasting classic and a pioneering work, George Pal’s 1953 alien invasion epic set the standard for visuals in SF movies. Unfortunately, in removing itself from H.G. Wells’ themes, the script loses both its poignancy and its dramatic functionality. 7/10

The Day the Earth Stood Still

The fate of the world hangs in the balance as the mysterious alien Klaatu arrives on a diplomatic mission to Earth with his deadly robot. Oscar winner Robert Wise’s “subversive” 1951 classic was a radical call for world peace in the midst of McCarthyist blacklistings. Possibly the best of the fifties SF films, this one holds up surprisingly well today. 10/10.
