We let me try:
The first thing that came in mind was Interstellar
but I know you watched that one the second one that came in was Enders Game also watched that one .So I need to dig deeper I rarely watch movies pre 2000 you know.
Hold on
The movie cannot be famous/ well-known.That makes it even harder gosh.But let's carry on
My picks goes to Prometheus
the reasons why:
Deep space exploration that pulls my hart string.
The thought that we are alone is this universe is quite absurd
there must some form of life out there which is at the same time exciting but also scary as hell.
I like always when the characters come against traces of an extinct civilzation.What is this time the cause of the end of that civilzation.The most I like about the movie is playing with topics like consciousness.A very sophisticated machine behaves very human like and shows human emotions and acts on those emotions sometimes.feels certain desire.Is it not illogical that a machine acts on emotions..Can you still call that a machine the line is getting blurry.What makes us us.
The movies put such thought above the surface that I remember it so vividly
and btw the movie got a plot twist
Great picks. Seen them all. But you got points for awesomeness: https://steemit.com/steembasicincome/@vimukthi/announcement-winners-of-my-hunt-for-underappreciated-science-fiction-hidden-gems-sbi-giveaway
