I’ve often wondered why it is that there’s so little variation in sci-fi movies. With some notable exceptions, if it’s got a big budget it will be low on ideas.
What struck me most was that out of 300 screenplays, only 13 were sci-fi/post apocalyptic and only 2 were set in space (though one assumes some of the ‘anonymous’ locations might be not-earth). Given how many sci-fi movies are made, they’re really coming from (%-wise) a small pool!
I’m no longer surprised at the lack of variation.
