Scariest Sci-fi Moviesroblist 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
The suspense kept you on the edge of your seat!
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 - Irina2932
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.
Alien sucks! The Thing is great...
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
Better movie, better pace than the two above.
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.
How is this scary? I was 12 when I saw it, no fright!
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?
this movie is so scary compared to I Am LEgend!
It was one of the best movies I've seen in a while.
Scary weird I dn't get it at all
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
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.
This should be No1. Not just the scariest SciFi movie, one of the scariest movies of any genre.
The scarest movie I ever watched in my life.
Sickness at its finest
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.
This movie wasn't even here. I'm shocked. "Invasion... " is one of the most creative and scary Sci-Fi films ever made - Irina2932
You guys should watch this movie - real masterpiece from Carpenter. And enough creepy - Alexandr
Excellent. They do not make them like that anymore
Awesome movie, wtched this all the time as a kid
Not the best alien film the best alien films are alien, alien 2, alien 4 and Prometheus
Oh god! That experiments scene! Scared the crap out of me! - Jetticus12
If it weren't for E.T. himself. - renatofgv
This movie should be THE SCARIEST Sci-Fi Movie Ever. It had me at the edge of my seat for the first 45 minutes. And the rest of the time I was riveted. Except for the Tim Robbins crap scenes.
I just love bug movies! It was great!
Enjoyed very much
This movie was a serious scare, it was based on a doomsday event that was going to happen in December 21, 2012, but thankfully, it never happened, so there, this movie is scrapped.
Gravity was such a suckish film, it wasn't even scary at all, it was totally unrealistic and fake everywhere.
Oh the HORROR! The story line makes me cringe and jump!
By far the best movie ever
Really really good classic film
We all know it's going to be scary, because there's this huge super weapon that will blow up star systems, destroying all of their planets, and killing many billions of people and lives on them, that will beat anything else.
Only because of the scene where the Death Star destroyed Alderaan, Princess Leia's home planet, as billions of people were blown to bits at once by that tragic event.
Not exactly as scary as the other two, but it was very scary, as Anakin Skywalker, aka Darth Vader, was burning on the hell planet Mustafar after losing to Obi Wan Kenobi., that scene was way too scary for many people, and caused an emotional outrage.
