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

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.

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.

Yeah, the aliens in Alien are friggen scary. But Predator is more advanced and carry awesome guns and knives!

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

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

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.

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

One of the most creepiest movies you will ever see epsessally where you see the alien on the roof!
