Alien body snatchers

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

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
