Top 10 Scariest Sci-fi Movies

When we think of Sci-Fi we think of Star Wars and computers etc. But Sci Fi does have a dark side to it, here is the list of Scariest Sci-Fi films of all time!

The Top Ten

Alien Alien Product Image

By far the scariest Sci-Fi movie ever made - scary locations, scary monster's look, scary score. Brilliant acting from the whole cast made it look even more impressive

Cursed me with insomniac and nightmares for weeks, and whenever the name "alien" is mentioned, my little kid-scary-first-encounter's memories return.

In its day the most unique movie ever made, a great combination of space, horror, suspense and drama.

Both Alien and Aliens are outstanding movies. I saw Aliens first and I just might like it better.

The Thing The Thing Product Image

All of the other sci-fi movies on this list are AMAZING, but none with the psychological, gut-ripping, gory, horrifying, suspenseful terror that The Thing provides for you.

I go back and fourth between this and Alien being the greatest horror movie of all time...but this one wins out.

No other movie with it's theme and music score could ever compete with this film best of all time

Easily number 1. Scarier than Alien!

Aliens Aliens  Product Image

Laugh out loud, the alien series in general is the best sci-fi ever! Predator sucks and is the only franchise coming to mind which I would like to discredit. All other sci-fi's are awesome though. Xenomorphs rule! They look great and have awesome abilities which, in my opinion, ranks them at the top of the evil alien list

so scary! even scarier than the first one! But the guns make me feel safe

Aliens is a great movie but it should be no. 10 cause its not scary at all I think the thing is the scariest and alien ressurection is the most disgusting and alien 3 also and alien is the scariest.

Better movie, better pace than the two above.

Predator Predator Product Image

Predator is my favorite Sci Fi/Action movie of all time, a solid performance by Arnie, great action, horror and plot twist, not to mention excellent score and endlessly memorable quotes.

Predator is AMAZING I have a movie like this one it is called alien vs predator

Could you wish for a more iconic creature?

How is this scary? I was 12 when I saw it, no fright!

28 Days Later 28 Days Later Product Image

this movie is so scary compared to I Am LEgend!

I Am Legend I Am Legend Product Image

It was one of the best movies I've seen in a while.

Scary weird I dn't get it at all

Cloverfield Cloverfield Product Image

You know even though we have problems with terrorists, it would be better and awesome if there's a real-life monster wrecking havoc in our country instead!

Not in the least enjoyable, although Goodman is great, as always

Signs Signs Product Image

This is the most underrated scary movie ever, saw it when I was 5 and didn't sleep til at least three days without a nightmare

I saw this when I was young too I still have nightmares about those those monsters

I hate this movie only because I saw it when I was 6 or 7 and I got so scared I cried

My papaw showed me this at 4 years old I still can't get over it.

Event Horizon Event Horizon Product Image

The scarest movie I ever watched in my life.

Sickness at its finest

This should be No1. Not just the scariest SciFi movie, one of the scariest movies of any genre.

I took a girl on our first date to see EH in theatres. Needless to say it was consequently our last date as well. The hell visualization was about as creepy as it gets. The theatrical version ended with Prodigy's "Funky Sh! t" Appropriate.
