15 Most Terrifying Movie Aliens Of All Time
6. Pod People (Invasion Of The Body Snatchers)
The deadliest thing about this lot is that is that they can hide in plain sight... well, y'know, after they're born out out slimy pods and kill their human lookalike. Yes, the 1978 remake of Invasion of the Body Snatchers really heightened the terrifying notion that an alien race can literally become you and dispose of you, all while you sleep.
Deadly alien spores that have escaped their dying planet, they find their way to San Francisco and single-handedly begin a purge of the human race by creating exact copies of their sleeping muse. Identical in almost every way possible, there is but one difference: They're simply devoid of human emotion.
With the evil intentions of wiping out the human race and harvesting their resources for themselves, they take survival of the fittest to a whole new level. And if that wasn't terrifying enough, the shrill screech they're capable of emitting will make the hairs on the back of your neck stand up every single time you even think about it.
