I am looking for a movie called sleepers, it was set on another plant. It had humanoid robots that killed the human population! If you could give me a year or any way to find the movie I would appriecate it.

I thought it was worth a shot to mention that there's a 1995 movie called Screamers that has robots (which become humanoid) that kill humans.
Screamers (1995) (http://www.imdb.com/title/tt0114367/)
