Another great British 50s scifi, dealing with mature themes of government conspiracy and control. It has something akin to the podpeople in Invasion of the Bodysnatchers, but these podpeople are ahead of the curve, and have already taken over government. It really packs a lot into its 80 minute running time, so has some narrative shortcuts that are really massive coincidences, but there’s some great stuff here…the police inspector about to tell all to someone in power, and noticing the alien scar and quickly changing the story, the sinister guards in gasmasks and helmets wielding machine guns, and the realisation the aliens are blocking the pipes with human bodies to stop oxygen poisoning them. A great paranoia piece of the time.
