Top 10 Scariest Sci-fi MoviesWhen 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!
Cursed me with insomniac and nightmares for weeks, and whenever the name "alien" is mentioned, my little kid-scary-first-encounter's memories return.
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
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.
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.
I'm a huge sci-fi/horror fan and I've seen most of these movies, but the thing is by far the scariest.
Easily number 1. Scarier than Alien!
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
What James Cameron does to make this terrifying is make you become emotionally invested in its two lead characters, (Ellen Ripley and Newt) and put these characters in dangerous circumstances with Xenomorphs, which are crazy as hell.
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.
Alien was a lot scarier, you had no idea what the creature was, the crew wasnt prepared, and the overall atmosphere and tone was a lot freakier. this movie was great as well, but FAR from scary.
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.
Yeah, the aliens in Alien are friggen scary. But Predator is more advanced and carry awesome guns and knives!
How is this scary? I was 12 when I saw it, no fright!
Could you wish for a more iconic creature?
It was one of the best movies I've seen in a while.
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
Oh my gosh freakiest alien movie ever, watched it before I went to sleep and couldn't stop thinking about the scene were bow says to her dad there's a monster outside and there's like a massive, buff, glaring figure like an impersonation of the devil and also the 7 year old birthday in Brazil on T.V. If that was shown o actual T.V. people all over the world would be crappin their pants honestly brilliant but damn creepy. God bless all who watch.
One of the most creepiest movies you will ever see epsessally where you see the alien on the roof!
My papaw showed me this at 4 years old I still can't get over it.
That scene at night in the cornfield... You know the one.
This should be No1. Not just the scariest SciFi movie, one of the scariest movies of any genre.
Sickness at its finest
I shat myself :/
You guys should watch this movie - real masterpiece from Carpenter. And enough creepy
Excellent. They do not make them like that anymore
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.
Not scary. But it is my favorite movie of all time. But it would be SO SCARY if this was in real life.
Not the best alien film the best alien films are alien, alien 2, alien 4 and Prometheus
