I have frustratingly vague memories of this because I literally saw two scenes of this and then had to switch channels because it wasn't among the movies my mother would let me watch. It was on the Sci-Fi channel, somewhere in the mid-90s. A man and a woman were fleeing ahead of a guy and his two goons. The guy was extremely pale, and I think older, possibly with white hair. The two goons were bumbling archetypes — I want to say that one of them was fairly chubby — and were dressed in stereotypical dystopian armor, you know, the sort of black stuff that looks like salvaged car parts.
The scene that sticks out in my mind was that the bad guys came upon a body, possibly of a fellow henchman, stuck inside this mucusy stuff, I think pink in color, and the main bad guy told the other two to extract the dead man's memory. What sticks out in my head was that, to remove the memories, they sucked out the brain using a vacuum cleaner hose, a big thick one like used in flowbees. I'm reasonably certain that it had prongs of some sort on the mouth of the hose, probably to lock it into the head. I have a vague memory of this happening inside a long white building, reminiscent of an elementary school, in the middle of a desolate wasteland.
