I'm trying to identify a sci-fi/horror film from the late 70's or 80's. It was live-action and takes place mainly on a spaceship or station. The film is very dark with a vibe similar to Alien (1979). I don't remember the plot (other than people getting killed off one-by-one), but I do remember that the robot/android on the ship was distinctive:
- Humanoid body, black or dark gray in color
- long, extendable neck with a head on the end (think the lamp from Pixar's logo, only black)
- had a human brain, and may have had a psychotic break as a result (pretty sure the robot was doing the killing IIRC)
Sorry, I know this isn't much to go on, but that's exactly why I'm having problems finding it.
