Best sci-fi movies...

[Worried Brown Eyes]

Soylent Green (wonder what that is?)

[Lost User]

By today's standards yes it's pretty poor, especially that scene where Klatu picks up the girl and she screams and faints. But ... when I first saw it in 1950 something I did think it was brilliant.

The 27th Day (1957) - IMDb[^].

[PeejayAdams]

Dark Star deserves a mention.

98.4% of statistics are made up on the spot.

[Nelviticus]

You seem to be missing: Aliens Blade Runner 2049 Dredd Flash Gordon Gravity Guardians of the Galaxy Inception Looper Moon Pitch Black Starship Troopers Sunshine Twelve Monkeys

[RobertHarris]

Soldier - An underestimated film with Kurt Russell in the lead role.

[MKJCP]

Certainly The Blob (1958 version) should be in there. Corny, freaky, weird, hilarious, classic.

[MKJCP]

Starship Troopers was so bad I couldn't finish watching, must have missed the good part.

[Slow Eddie]

Buckaroo Banzai across the 8th Dimension Repo Man

"Newer" is NOT automatically better, only Different. (And more complex and bug ridden when it comes to all of the "boutique" languages / frameworks out there

[Alex Sanchez SM]

Invasion Of The Body Snatchers (both the 50s and the 70s versions) Might be more horror than SF. Silent Running Maybe someone's already suggested them (i'm catching up with the thread)

[Ed Thompson 210]

Two movies that fit the catagory 'Science Fiction' that weren't special effects or action films, but I always thought were well thought out science fiction plots: Colossus the Forbin Project The Andromeda Strain I especially liked Colossus because of all of the 60's 'computer taking over the world plots' on TV shows and movies, which were all were defeated by asking the computer some vague question like 'why' or 'compute Pi to the last digit'.

---someday something witty will be placed here----

This is CodeProject, and no one mentions Hitchhiker's Guide to the Galaxy? I think you all should get a down-vote of 42!!

[Paul Kemner]

Colossus had some interesting ideas. It and the Soviet computer communicated starting with simple math and developing their own undecipherable language. And at the end it appears that its only goal is to prevent war, but we don't see where the line between war and any violence is. What happens next, assuming the computer is unbeatable, would make an interesting SF novel. Or maybe it leads to ST:tOS?

[Paul Kemner]

Though the original BBC radio play is even better.

[Foothill]

Honorable mention to Akira[^], 1988.

if (Object.DividedByZero == true) { Universe.Implode(); } Meus ratio ex fortis machina. Simplicitatis de formae ac munus. -Foothill, 2016

[MRupleyJ]

Never heard of that. Time to go find it and listen. Thanks!!

[Paul Kemner]

The reason Arthur and Ford were cast into space by the Vogons: Adams thought the radio series was being cancelled, so he killed the characters off in what he thought was the last episode. He was wrong, and needed to bring the characters back. The result: Infinite Improbability Drive.

[sam silvercreek]

You forgot [Idiocracy](http://www.imdb.com/title/tt0387808/) It was originally released as a Sci-Fi/Comedy, but seems to have become a documentary in recent years. :sigh:

[Paul Kemner]

Akira was hugely influential, but I found it to be a snoozefest. Royal Space Force: The Wings of Honnêamise (1987), while not popular in Japan, is worth a watch. It's about the first space launch on an alternate Earth- pretty much "The Wrong Stuff" because the effort has no prestige and the government expects it to fail.

Solaris Stalker Metropolis and for the lighter moments The Adventures of Buckaroo Banzai Across the Eighth Dimension
