THE LAST SCREAM YOU HEAR WILL BE YOUR OWN.
SIRIUS 6B, the year 2078. On a distant mining planet ravaged by a decade of war, scientists have created the perfect weapon: a blade-wielding, self-replicating race of killing devices known as Screamers designed for one purpose only -- to hunt down and destroy all enemy life forms.
I love this movie. The action is fun but it also has a deeper subtext about consciousness and whether machines can think, etc. It is based on the short story Second Variety by Philip K. Dick.
It's really shocking how many Philip K. Dick stories have been made into films. Off the top of my head, the ones I can remember are:
Total Recall (two versions)
Blade Runner
Screamers
A Scanner Darkly
Paycheck
Imposter
The Man in the High Castle (a streaming series, not a film)
The Minority Report
...And I'm sure that I'm missing at least some. If he hadn't died so young, he would have been insanely wealthy from how many times his stories have been adapted into major films.
